These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. If Military or Aerospace specified devices are required, contact the Texas Instruments Sales Office or Distributors for availability and specifications. In the application the HS node is clamped by the body diode of the external lower N-MOSFET, therefore the HS node will generally not exceed -1 V. However, in some applications, board resistance and inductance may result in the HS node exceeding this stated voltage transiently. If negative transients occur, the HS voltage must never be more negative than VDD - 15 V. For example if VDD = 10 V, the negative transients at HS must not exceed -5 V. 7.2 ESD Ratings VALUE Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) V(ESD) (1) (2) Electrostatic discharge Machine Model (MM) (2) UNIT 2000 Option A 50 Option B and C 100 V The Human Body Model (HBM) is a 100-pF capacitor discharged through a 1.5-k resistor into each pin. 2 kV for all pins except Pin 2, Pin 3 and Pin 4 which are rated at 1000 V for HBM.

The outputs are independently controlled with CMOS input thresholds(LM5101A/B/C) or TTL input thresholds(LM5101A/B/C). The floating high-side driver is capable of working with supply voltages up to 100 V. An integrated high voltage diode is provided to charge high side gate drive bootstrap capacitor. A robust level shifter operates at high speed while consuming low power and providing clean level transitions from the control logic to the high side gate driver. Under-voltage lockout is provided on both the low side and the high side power rails. 8.2 Functional Block Diagram HB UVLO LEVEL SHIFT DRIVER HO HS HI VDD UVLO LI DRIVER LO GND 8.3 Feature Description 8.3.1 Start-up and UVLO Both high and low-side drivers include under voltage lockout (UVLO) protection circuitry which monitors the supply voltage (VDD) and bootstrap capacitor voltage (VHB-HS) independently. The UVLO circuit inhibits each driver until sufficient supply voltage is available to turn on the external MOSFETs, and the built-in UVLO hysteresis prevents chattering during supply voltage transitions. When the supply voltage is applied to the VDD pin of the LM5100A/B/C and LM5101A/B/C, the outputs of the low-side and high-side are held low until VDD exceeds the UVLO threshold, typically about 6.6 V. Any UVLO condition on the bootstrap capacitor will disable only the high-side output (HO). 8.3.2 Level Shift The level shift circuit is the interface from the high-side input to the high-side driver stage which is referenced to the switch node (HS). The level shift allows control of the HO output referenced to the HS pin and provides excellent delay matching with the low-side driver. 14 Submit Documentation Feedback Copyright (c) 2006-2015, Texas Instruments Incorporated Product Folder Links: LM5100A LM5100B LM5100C LM5101A LM5101B LM5101C LM5100A, LM5100B, LM5100C LM5101A, LM5101B, LM5101C www.ti.com SNOSAW2Q - SEPTEMBER 2006 - REVISED NOVEMBER 2015 Feature Description (continued) 8.3.3 Bootstrap Diode The bootstrap diode necessary to generate the high-side bias is included in the LM5100/1 family. The diode anode is connected to VDD and cathode connected to VHB. With the VHB capacitor connected to HB and the HS pins, the VHB capacitor charge is refreshed every switching cycle when HS transitions to ground. The boot diode provides fast recovery times, low diode resistance, and voltage rating margin to allow for efficient and reliable operation. 8.3.4 Output Stages The output stages are the interface to the power MOSFETs in the power train. High slew rate, low resistance, and high peak current capability of both output drivers allow for efficient switching of the power MOSFETs. The low-side output stage is referenced from VDD to VSS and the high-side is referenced from VHB to VHS. 8.4 Device Functional Modes The device operates in normal mode and UVLO mode. See Start-up and UVLO for more information on UVLO operation mode. In normal mode, the output stage is dependent on the states of the HI and LI pins. Table 1.

TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information To affect fast switching of power devices and reduce associated switching power losses, a powerful gate driver is employed between the PWM output of controllers and the gates of the power semiconductor devices. Also, gate drivers are indispensable when it is impossible for the PWM controller to directly drive the gates of the switching devices. With the advent of digital power, this situation will be often encountered because the PWM signal from the digital controller is often a 3.3-V logic signal which cannot effectively turn on a power switch. Level shifting circuitry is needed to boost the 3.3-V signal to the gate-drive voltage (such as 12 V) in order to fully turn on the power device and minimize conduction losses. Traditional buffer drive circuits based on NPN/PNP bipolar transistors in totem-pole arrangement, being emitter follower configurations, prove inadequate with digital power because they lack level-shifting capability. Gate drivers effectively combine both the level-shifting and buffer-drive functions. Gate drivers also find other needs such as minimizing the effect of high-frequency switching noise by locating the high-current driver physically close to the power switch, driving gate-drive transformers and controlling floating power-device gates, reducing power dissipation and thermal stress in controllers by moving gate charge power losses from the controller into the driver. The LM5100A/B/C and LM5101A/B/C are the high voltage gate drivers that are designed to drive both the highside and low-side N-Channel MOSFETs in a half-bridge/full bridge configuration or in a synchronous buck circuit. The floating high side driver is capable of operating with supply voltages up to 100 V. This allows for N-Channel MOSFET control in half-bridge, full-bridge, push-pull, two switch forward and active clamp topologies. The outputs are independently controlled. Each channel is controlled by its respective input pins (HI and LI), allowing full and independent flexibility to control on and off state of the output. 9.2 Typical Application Optional external fast recovery diode VIN VCC RBOOT DBOOT HB RGATE HO VDD VDD CBOOT PWM Controller 0.1 F HI OUT1 HS T1 LM5101A LI OUT2 LO RGATE 1.0 F VSS Figure 25.

It is recommended to place the bootstrap capacitor as close to the HB and HS pins as possible. CBOOT = 100 nF (4) As a general rule the local VDD bypass capacitor should be 10 times greater than the value of CBOOT. CVDD = 10 x CBOOT = 1 F (5) The bootstrap and bias capacitors should be ceramic types with X7R dielectric. The voltage rating should be twice that of the maximum VDD to allow for loss of capacitance once the devices have a DC bias voltage across them and to ensure long-term reliability of the devices.

The charging of the capacitor involves high peak currents, and therefore transient power dissipation in the internal bootstrap diode may be significant and dependent on its forward voltage drop. Both the diode conduction losses and reverse recovery losses contribute to the total losses in the gate driver and need to be considered in the gate driver IC power dissipation. For high frequency and high capacitive loads, it may be necessary to consider using an external bootstrap diode placed in parallel with internal bootstrap diode to reduce power dissipation of the driver. For the selection of external bootstrap diodes for LM510x device, please refer to the application note SNVA083. Bootstrap resistor RBOOT is selected to reduce the inrush current in DBOOT and limit the ramp up slew rate of voltage of HB-HS. It is recommended that RBOOT is between 2 and 10 .

The gate driver losses are related to the switching frequency (fsw), output load capacitance on LO and HO (CL), and supply voltage (VDD). The gate charge losses can be calculated by Equation 11. 2 PDGATES = 2 VDD CL fsw There are some additional losses in the gate drivers due to HO outputs.

Since each of these events happens once per cycle, the diode power loss is proportional to frequency. Larger capacitive loads require more energy to recharge the bootstrap capacitor resulting in more losses. Higher input voltages (VIN) to the half bridge result in higher reverse recovery losses. The following plot was generated based on calculation and lab measurements of the diode recovery time and current under several operating conditions. This can be useful for approximating the internal diode power dissipation. If the diode losses can be significant, an external diode placed in parallel with the internal bootstrap diode can be helpful to reduce power dissipation within the IC. 0.100 POWER (W) CL = 4400 pF CL = 0 pF 0.010 0.001 1 10 100 1000 SWITCHING FREQUENCY (kHz) Figure 27.

HI/LI to HO/LO Turnon Propagation Delay Figure 29. HI/LI to HO/LO Turnoff Propagation Delay 10 Power Supply Recommendations The bias supply voltage range for which the device is rated to operate is from 9 V to 14 V. The lower end of this range is governed by the internal under voltage-lockout (UVLO) protection feature on the VDD pin supply circuit blocks. Whenever the driver is in UVLO condition when the VDD pin voltage is below the VDDR supply start threshold, this feature holds the output low, regardless of the status of the inputs. The upper end of this range is driven by the 18-V absolute maximum voltage rating of the VDD pin of the device (which is a stress rating). Keeping a 4-V margin to allow for transient voltage spikes, the maximum recommended voltage for the VDD pin is 14 V. The UVLO protection feature also involves a hysteresis function. This means that when the VDD pin bias voltage has exceeded the threshold voltage and device begins to operate, and if the voltage drops, then the device continues to deliver normal functionality unless the voltage drop exceeds the hysteresis specification VDDH. Therefore, ensuring that, while operating at or near the 9-V range, the voltage ripple on the auxiliary power supply output is smaller than the hysteresis specification of the device is important to avoid triggering device shutdown. During system shutdown, the device operation continues until the VDD pin voltage has dropped below the threshold (VDDR - VDDH), which must be accounted for while evaluating system shutdown timing design requirements. Likewise, at system start up, the device does not begin operation until the VDD pin voltage has exceeded above the VDDR threshold. The quiescent current consumed by the internal circuit blocks of the device is supplied through the VDD pin. Keep in mind that the charge for source current pulses delivered by the LO pin is also supplied through the same VDD pin. As a result, every time a current is sourced out of the LO pin a corresponding current pulse is delivered into the device through the VDD pin. Thus ensuring that a local bypass capacitor is provided between the VDD and GND pins and located as close as possible to the device for the purpose of decoupling is important. A low ESR, ceramic surface mount capacitor is necessary. TI recommends using two capacitors between VDD and GND: a 100-nF ceramic surface-mount capacitor that can be nudged very close to the pins of the device and another surface-mount capacitor in the range 0.22 F to 10 F added in parallel. In a similar manner, the current pulses delivered by the HO pin are sourced from the HB pin. Therefore, a 0.022-F to 1-F local decoupling capacitor is recommended between the HB and HS pins. 20 Submit Documentation Feedback Copyright (c) 2006-2015, Texas Instruments Incorporated Product Folder Links: LM5100A LM5100B LM5100C LM5101A LM5101B LM5101C LM5100A, LM5100B, LM5100C LM5101A, LM5101B, LM5101C www.ti.com SNOSAW2Q - SEPTEMBER 2006 - REVISED NOVEMBER 2015 11 Layout 11.1 Layout Guidelines The optimum performance of high and low-side gate drivers cannot be achieved without taking due considerations during circuit board layout. Following points are emphasized. 1. Low-ESR/ESL capacitors must be connected close to the IC, between VDD and VSS pins and between the HB and HS pins to support the high peak currents being drawn from VDD during turnon of the external MOSFET. 2. To prevent large voltage transients at the drain of the top MOSFET, a low ESR electrolytic capacitor must be connected between MOSFET drain and ground (VSS). 3. In order to avoid large negative transients on the switch node (HS pin), the parasitic inductances in the source of top MOSFET and in the drain of the bottom MOSFET (synchronous rectifier) must be minimized. 4. Grounding Considerations: - The first priority in designing grounding connections is to confine the high peak currents that charge and discharge the MOSFET gate into a minimal physical area. This will decrease the loop inductance and minimize noise issues on the gate terminal of the MOSFET. The MOSFETs should be placed as close as possible to the gate driver. - The second high current path includes the bootstrap capacitor, the bootstrap diode, the local ground referenced bypass capacitor and low-side MOSFET body diode. The bootstrap capacitor is recharged on a cycle-by-cycle basis through the bootstrap diode from the ground referenced VDD bypass capacitor. The recharging occurs in a short time interval and involves high peak current. Minimizing this loop length and area on the circuit board is important to ensure reliable operation. A recommended layout pattern for the driver is shown in Figure 30. If possible a single layer placement is preferred. 11.2 Layout Example Recommended Layout for Driver IC and Passives VDD LO HB VSS SO PowerPAD-8 LI HS HI D LO N To Hi-Side FET Multi Layer Option G HO HS HO Single Layer Option HO To Low-Side FET Figure 30.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. TI's published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and services. Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyers and others who are developing systems that incorporate TI products (collectively, "Designers") understand and agree that Designers remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products used in or for Designers' applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will thoroughly test such applications and the functionality of such TI products as used in such applications. TI's provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, "TI Resources") are intended to assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any way, Designer (individually or, if Designer is acting on behalf of a company, Designer's company) agrees to use any particular TI Resource solely for this purpose and subject to the terms of this Notice. TI's provision of TI Resources does not expand or otherwise alter TI's applicable published warranties or warranty disclaimers for TI products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically described in the published documentation for a particular TI Resource. Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. TI RESOURCES ARE PROVIDED "AS IS" AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL PROPERTY RIGHTS.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers' own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection. Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer's noncompliance with the terms and provisions of this Notice.
