Pin Description

Pin Number

Pin Name

Pin Function

1V+

Supply. Must be decoupled to isolate from large transients caused by the

power MOSFET drain. 10µF is recommended close to pins 1 and 4.

2

Input

Turns on power MOSFET when taken above (or below) threshold (1.0V

typical). Pin 2 requires ~ 1µA to switch.

3

Source

Connects to source lead of power MOSFET and is the return for the gate

clamp zener. Pin 3 can safely swing to –20V when turning off inductive

loads.

4

Ground

5

Gate

Drives and clamps the gate of the power MOSFET.

6, 7, 8

NC

Not internally connected.
