The TC4431 is a 30V CMOS inverting MOSFET driver capable of sourcing and sinking up to 1.5A peak output current. It operates from a 4.5V to 30V supply and drives 1000pF loads in 25ns with typical delay times under 78ns. The device has a low output impedance of 7Ω, supply current of 2.5mA with a logic high input and 300µA with a logic low input, and includes under-voltage lockout that holds the output low when supply voltage falls below 7V. It is latch-up protected to withstand over 300mA reverse current and is ESD protected to 4kV. The part is available in 8-pin PDIP, SOIC, and CERDIP packages.
The TC4431/4432 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 4 kV 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.
