1 / 17 page 2003 Microchip Technology Inc. DS21424C-page 1 M TC4431/TC4432 Features • High Peak Output Current – 1.5A • Wide Input Supply Voltage Operating Range: - 4.5V to 30V • High Capacitive Load Drive Capability: - 1000 pF in 25 nsec • Short Delay Times – <78 nsec Typ. • Low Supply Current: - With Logic ‘1’ Input – 2.5 mA - With Logic ‘0’ Input – 300 µA • Low Output Impedance – 7 Ω • Latch-Up Protected: Will Withstand >300 mA Reverse Current • ESD Protected – 4 kV Applications • Small Motor Drive • Power MOSFET Driver • Driving Bipolar Transistors Package Types 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 300 mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 4 kV of electrostatic discharge. Undervoltage lockout circuitry forces the output to a ‘low’ state when the input supply voltage drops below 7V. For operation at lower voltages, disable the lockout and start-up circuit by grounding pin 3 (LOCK DIS); for all other situations, pin 3 should be left floating. The under-voltage lockout and start-up circuit gives brown- out protection when driving MOSFETS.
