TC4431/TC4432

1.5A High-Speed 30V MOSFET Drivers

Features

General Description

• 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:

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.

- With Logic ‘1’ Input – 2.5 mA

- With Logic ‘0’ Input – 300 µA

• Low Output Impedance – 7Ω

• Latch-Up Protected: Will Withstand >300 mA

Reverse Current

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.

• ESD Protected – 4 kV

Applications

• Small Motor Drive

• Power MOSFET Driver

• Driving Bipolar Transistors
