Pin Description

Pin Number

Pin Name

Pin Function

1

EN

Enable (Input): Logic-compatible enable input. High input > 2.1V typical.

Low input <1.9V typical (-1 active high, -2 active low).

2

FLG

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

UVLO and thermal shutdown.

3

GND

Ground: Supply return.

4, 5

NC

Not internally connected. (For pin compatibility with the MIC2505, connect

pin 7 to pin 5 and leave pin 4 unconnected.)

7

IN

Supply Input: Output MOSFET drain. Also supplies IC’s internal circuitry.

Connect to positive supply.

6, 8

OUT

Switch Output: Output MOSFET source. Typically connect to switched side

of load.
