NAME
FUNCTION
1
IN
Input. Bypass with a 0.1F ceramic capacitor to ground.
2
5
GND
Ground
3
6
ON
Active-High Switch-On Input. A logic high turns the switch on.
44
FLAG
Fault Output. This open-drain output goes low when the device stays in forward or reverse current limit
for more than the blanking time period.
FLAG is high impedance when a fault is not present or when
ON is low.
5
3
SEL
Current-Limit Threshold Selection. Connect to logic-low level or leave floating to select 200mA current-
limit threshold. Connect to logic-high level to select 500mA current-limit threshold.
6
2
OUT
Switch Output. Bypass with a 0.1F ceramic capacitor to ground.
