Pin Function

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

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

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

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

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.

Drives and clamps the gate of the power MOSFET.

Not internally connected.
