General Description
The TC4431/TC4432 are 30V CMOS buffer/drivers
suitable 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.
Under-voltage lockout circuitry forces the output to a
"low" state when the input supply voltage drops below
7V. For operation in lower voltages, disable the lockout
and start-up circuit by grounding pin 3 (LOCK DIS); for
all other situations, pin 3 (LOCK DIS) should be left
floating. The under-voltage lockout and start-up circuit
gives brown out protection when driving MOSFETS.
