FUNCTION
Switch A Output. P-channel MOSFET drain. Bypass OUT A with a 0.1 μ F capacitor to ground.
Switch B Output. P-channel MOSFET drain. Bypass OUT B with a 0.1 μ F capacitor to ground.
Set Current-Limit Input. A resistor from SET A to ground sets the current limit for switch A. See Setting the
Current Limit section.
Active-Low Switch A On Input. A logic low turns switch A on.
Ground
Set Current-Limit Input. A resistor from SET B to ground sets the current limit for switch B. See Setting the
Current Limit section.
Input, Switches A and B. P-channel MOSFET source. Bypass IN with a 1 μ F capacitor to ground.
Active-Low Switch B On Input. A logic low turns switch B on.
