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.
