REVERSE BATTERY
low as -16 V. Under these conditions, the output’s gate is
enhanced to keep the junction temperature less than 150°C.
The ON resistance of the output is fairly similar to that in the
Normal mode. No additional passive components are
required.

GROUND DISCONNECT PROTECTION
ground, the device protects itself and safely turns OFF the
output regardless the state of the output at the time of
disconnection. A 10 kΩ resistor needs to be added between
the WAKE pin and the rest of the circuitry in order to ensure
that the device turns off in case of ground disconnect and to
prevent this pin to exceed its maximum ratings.
