Pin Function
Supply; must be decoupled to isolate from large transients caused by the
power FET drain. 10 F is recommended close to pins 1 and 4.
Turns on power MOSFET when taken above threshold (3.5V typical).
Requires <1 A 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. Will be clamped to approxi-
mately –0.7V by an internal diode when turning off inductive loads.
Optional 1nF capacitors reduce gate turn-on time; C2 has dominant effect.
