Pin Function

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

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

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

Requires <1 µA to switch.

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.

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

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