1

FLG

Fault Flag (Output): Active-low, open-drain output. Indicates overcurrent and

thermal shutdown switch conditions.

2, 7

OUT

Switch Output: Output MOSFET source. Typically connected to switched

side of load. Pin 2 and 7 must be connected together externally.

3

IN

Supply Voltage Input. Supply to switch and regulator. Connect to positive

supply.

4

3VOUT

3.3V Regulator Output

5

GND

Ground: Supply return.

6

3VEN

Regulator Enable (Input): Logic-compatible input. Logic high = enable, logic

low or open = shutdown. Do not float.

8

EN

Switch 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.
