1 / 14 page 2002 Microchip Technology Inc. DS21424B-page 1 M TC4431/TC4432 Features • High Peak Output Current – 1.5A • Wide Operating Range - 4.5V to 30V • High Capacitive Load Drive Capability – 1000pF in 25nsec • Short Delay Times – <78nsec Typ. • Low Supply Current: - With Logic "1" Input – 2.5mA - With Logic "0" Input – 300 µA • Low Output Impedance – 7 Ω • Latch-Up Protected: Will Withstand >300mA Reverse Current • ESD Protected – 4kV Applications • • • Device Selection Table Package Type 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. Part Number Package Temp.
