Dual, Current-Limited, High-Side P-Channel
Switches with Thermal Shutdown
______________________________________________________________Pin Description
PIN NAME
FUNCTION
1
OUT A Switch A Output. P-channel MOSFET drain. Bypass OUT A with a 0.1µF capacitor to ground.
2
OUT B Switch B Output. P-channel MOSFET drain. Bypass OUT B with a 0.1µF capacitor to ground.
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 Limit section.
4
ONA Active-Low Switch A On Input. A logic low turns switch A on.
5
GND 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 Limit section.
7
IN
Input, Switches A and B. P-channel MOSFET source. Bypass IN with a 1µF capacitor to ground.
8
ONB Active-Low Switch B On Input. A logic low turns switch B on.
