DIP Pin Number

Pin Name

Pin Function

12, 10

Supply; must be decoupled to isolate from large transients caused by the

power FET drain. 10

µF is recommended close to pins 1 and 4.

14, 11

Input

Turns on power MOSFET when taken above threshold (3.5V typical).

Requires <1

µA to switch.

2, 5

Source

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

zener. Can safely swing to –10V when turning off inductive loads.

3

Ground

4, 6

Gate

Drives and clamps the gate of the power FET. Clamped to approximately –

0.7V by an internal diode when turning off inductive loads.

–0.5V to 36V
