GENERAL DESCRIPTION
able for use in high-side driver applications. They will not
latch up under any conditions within their power and voltage
ratings. They can accept, without damage or logic upset, up
to 300mA of reverse current (of either polarity) being forced
back into their outputs. All terminals are fully protected
against up to 4kV of electrostatic discharge.

Maximum startup V
operation at lower voltages, the LOCK DIS, Pin 3 can be
grounded to disable the lockout and start-up circuit. The
under-voltage lockout and start-up circuit gives brown out
protection when driving MOSFETS.
