Reverse battery protection FET gate drive.
This pin is connected to the bootstrap capacitor.
Slew-rate Control of the switching regulator.
These pins are the source of the internal power switch (N-channel
MOSFET).
Voltage supply to the IC (external reverse battery protection needed in
some applications).
This pin is the keep alive supply input.
External capacitor reservoir of the internal charge pump.
Keep-Alive Memory (standby) supply output.
This is a V
This pin is also the output of the V
This pin can be used also as an additional standby regulator without the
external pass transistor.
This pin is a ground.
This pin is the ignition switch control input pin. It contains an internal
protection diode.
