TC4423M/TC4424M/TC4425M

3A Dual High-Speed Power MOSFET Drivers

General Description

Features

• High Peak Output Current: 3A

• Wide Input Supply Voltage Operating Range:

- 4.5V to 18V

The TC4423M/TC4424M/TC4425M devices are a

family of 3A, dual output buffers/MOSFET drivers. Pin-

compatible with both the TC4426M/TC4427M/

TC4428M and TC4426AM/4427AM/4428AM families

(dual 1.5A drivers), the TC4423M/TC4424M/TC4425M

family has an increased latch-up current rating of 1.5A,

making them even more robust for operation in harsh

electrical environments.

• High Capacitive Load Drive Capability:

- 1800 pF in 25 ns

• Short Delay Times: <40 ns (typ)

• Matched Rise/Fall Times

• Low Supply Current:

As MOSFET drivers, the TC4423M/TC4424M/

TC4425M can easily charge 1800 pF gate capacitance

in under 35 nsec, while providing low enough

impedances in both the on and off states to ensure the

MOSFET's intended state will not be affected, even by

large transients.

- With Logic ‘1’ Input – 3.5 mA (Max)

- With Logic ‘0’ Input – 350 µA (Max)

• Low Output Impedance: 3.5Ω (typ)

• Latch-Up Protected: Will Withstand 1.5A Reverse

Current

The TC4423M/TC4424M/TC4425M inputs may be

driven directly from either TTL or CMOS (2.4V to 18V).

In addition, 300 mV of hysteresis is built-in to provide

noise immunity and to allow the device to be driven

from slowly rising or falling waveforms.

• Logic Input: Will Withstand Negative Swing Up To

• ESD Protected: 4 kV

• Pin-compatible with the TC4426M/TC4427M/

TC4428M and TC4426AM/TC4427AM/

TC4428AM devices

Package Types

• Wide Operating Temperature Range:

- -55°C to +125°C
