NCP302, NCP303 Voltage Detector Series with Programmable Delay The NCP302 and NCP303 series are second generation ultra-low current voltage detectors that contain a programmable time delay generator. These devices are specifically designed for use as reset controllers in portable microprocessor based systems where extended battery life is paramount. Each series features a highly accurate under voltage detector with hysteresis and an externally programmable time delay generator. This combination of features prevents erratic system reset operation. The NCP302 series consists of complementary output devices that are available with either an active high or active low reset. The NCP303 series has an open drain N-channel output with an active low reset output. The NCP302 and NCP303 device series are available in the TSOP-5 package with seven standard under voltage thresholds. Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured. http://onsemi.com 5 1 TSOP-5 SN SUFFIX CASE 483 PIN CONNECTIONS AND MARKING DIAGRAM Features Quiescent Current of 0.5 A Typical High Accuracy Under Voltage Threshold of 2.0% Externally Programmable Time Delay Generator Wide Operating Voltage Range of 0.8 V to 10 V Complementary or Open Drain Output Active Low or Active High Reset 1 Input 2 Ground 3 4 N.C. xxx = 302 or 303 Y = Year W = Work Week (Top View) Typical Applications * * * * 5 CD xxxYW * * * * * * Reset Output Microprocessor Reset Controller Low Battery Detection Power Fail Indicator Battery Backup Detection ORDERING INFORMATION See detailed ordering and shipping information in the ordering information section on page 2 of this data sheet.

NCP302/3 Series Delay Resistance versus Temperature 100 NCP302, NCP303 OPERATING DESCRIPTION Vin will again return to its nominal level and become greater than the VDET+. The voltage detector will turn off the N-channel MOSFET and allow pullup resistor RD to charge external capacitor CD, thus creating a programmable delay for releasing the reset signal. When the voltage at Pin 5 exceeds the inverter/buffer threshold, typically 0.675*Vin, the reset output will revert back to its original state. The reset output time delay versus capacitance is shown in Figures 11 through 13. The voltage detector and inverter/buffer have built-in hysteresis to prevent erratic reset operation. Although these device series are specifically designed for use as reset controllers in portable microprocessor based systems, they offer a cost-effective solution in numerous applications where precise voltage monitoring and time delay are required. Figures 37 through 39 show various application examples. The NCP302 and NCP303 series devices consist of a precision voltage detector that drives a time delay generator. Figures 36 and 37 show a timing diagram and a typical application. Initially consider that input voltage Vin is at a nominal level and it is greater than the voltage detector upper threshold (VDET+). The voltage at Pin 5 and capacitor CD will be at the same level as Vin, and the reset output (Pin 1) will be in the high state for active low devices, or in the low state for active high devices. If there is a power interruption and Vin becomes significantly deficient, it will fall below the lower detector threshold (VDET-) and the external time delay capacitor CD will be immediately discharged by an internal N-channel MOSFET that connects to Pin 5. This sequence of events causes the Reset output to be in the low state for active low devices, or in the high state for active high devices. After completion of the power interruption, Input Voltage, Pin 2 Vin VDET+ VDET- Vin Capacitor, Pin 5 Reset Output (Active Low), Pin 1 0.675*Vin Vin VDET- 0V Reset Output (Active High), Pin 1 Vin VDET- 0V tD2 Figure 36.
