Pin Description
PIN NUMBER
PIN NAME PIN FUNCTION
Enable (input)
: Logic-compatible enable input. High input >2.1V typical.
Low input <1.9V typical (-1 active high, -2 active low). Do not float.
Fault Flag (Output)
: Active-low, open-drain output. Indicates overcurrent, UVLO, and
thermal shutdown.
GND
Ground
: Supply return.
Supply Input
: Output MOSFET source. Also supplies IC's internal circuitry. Connect to
positive supply.
OUT(A/B)
Switch Output
: Output MOSFET drain. Typically connect to switched side of load.
