NAME
FUNCTION
1—
4
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.
22
GND
Ground
3
ON
Active-High Switch On Input. A logic high turns the switch on.
4

N.C.
No Connection. Not internally connected.

IN
Input. Bypass IN with a 0.1F ceramic capacitor to ground.

OUT
Switch Output. Bypass OUT with a 0.1F ceramic capacitor to ground.
——
EP
Exposed paddle. Connect EP to a large ground plane to maximize
thermal performance. EP is not intended as an electrical connection
point. (TDFN Package only.)
