VC=2.7V VC=2.7V -100 VC=0.4V mA V 2 -100 mA VC=0.4V V A A *1: IS1 1 and IS1 2 are specified at the 5% drop points of output voltages VO1 and VO2 on the condition that VIN = the condition of overcurrent protection starting current, IO = 10 mA. *2: Output is OFF when the output control terminal VC is open. Each input level is equivalent to LS-TTL. Therefore, the devices can be driven directly by LS-TTLs. Channels 1 and 2 are turned on or off at the same time. 110 IC SI-3000KWD Series External Dimensions (Unit : mm) Case temperature measurement point 10.0 0.2 (4.4) 0.2 1.3 +0.10 -0.05 (6.8) 0.1 0.2 (R0.3) 0.2 4.9 2.54 0.3 2.0 2.4 (R0.3) (0.75) 0.2 0.1 15.3 0.3 0.3 9.2 15.3 0.15 0.1 (3) (3) 4.9 0.88 0.2 (4.6) (2xR0.45) (3) 0.2 0.2 (1.75) 4.5 3-R0.3 1.5 Dp: 0.2 (8.0) 1.2 (0.4) 9.9 (15) 9.2 0.2 0~6 (0.5) 0.1 0.1 (1.7 0.8 0.25 (1.7 ) 0.25 ) 1 2 3 4 0.25 (1.7 5 (3) (3) 2-R0.3 10.0 ) 0.8 0.25 (1.7 ) Pin Assignment q VC w VO1 e GND r VIN t VO2 0.02 Block Diagram VIN VOUT1 2 4 + CIN Drive REF + OCP ON/ OFF VC 1 + - AMP2 COUT1 - + TSD - + VOUT2 5 + Drive COUT2 + OCP AMP2 - GND 3 Ta-PD Characteristics 3.5 Copper Laminate Area 40 x 40mm Power Dissipation PD (W) 3 2.5 2 ( j-a:33.3C/W) Copper Laminate Area 20 x 40mm ( j-a:37C/W) Copper Laminate Area 20 x 20mm ( j-a:44C/W) Copper Laminate Area 10 x 10mm ( j-a:53C/W) 1.5 1 0.5 0 -25 0 25 50 75 100 125 Ambient Temperature Ta (C) IC 111
