NAME
FUNCTION
1
OUT A
Switch A Output. P-channel MOSFET drain. Bypass OUT A with a 0.1
μ
F capacitor to ground.
2
OUT B
Switch B Output. P-channel MOSFET drain. Bypass OUT B with a 0.1
μ
F capacitor to ground.
PIN
3
SET A
Set Current-Limit Input. A resistor from SET A to ground sets the current limit for switch A. See Setting the
Current Limitsection.
4
ONA
Active-Low Switch A On Input. A logic low turns switch A on.
8
ONB
Active-Low Switch B On Input. A logic low turns switch B on.
7
IN
Input, Switches A and B. P-channel MOSFET source. Bypass IN with a 1
μ
F capacitor to ground.
6
SET B
Set Current-Limit Input. A resistor from SET B to ground sets the current limit for switch B. See Setting the
Current Limitsection.
