TC4426AM/TC4427AM/TC4428AM

1.5A Dual High-Speed Power MOSFET Drivers

Features

General Description

• High Peak Output Current: 1.5A

• Wide Input Supply Voltage Operating Range:

- 4.5V to 18V

The TC4426AM/TC4427AM/TC4428AM are improved

versions of the earlier TC4426M/TC4427M/TC4428M

family of MOSFET drivers. In addition to matched rise

and fall times, the TC4426AM/TC4427AM/TC4428AM

devices have matched leading and falling edge

propagation delay times.

• High Capacitive Load Drive Capability:

- 1000 pF in 25 ns (typ.)

• Short Delay Times: 30 ns (typ.)

• Matched Rise, Fall and Delay Times

• Low Supply Current:

These devices are highly latch-up resistant under any

conditions within their power and voltage ratings. They

are not subject to damage when up to 5V of noise

spiking (of either polarity) occurs on the ground pin.

They can accept, without damage or logic upset, up to

500 mA of reverse current (of either polarity) being

forced back into their outputs. All terminals are fully

protected against Electrostatic Discharge (ESD) up to

4 kV.

- With Logic ‘1’ Input – 1 mA (typ.)

- With Logic ‘0’ Input – 100 µA (typ.)

• Low Output Impedance: 7Ω (typ.)

• Latch-Up Protected: Will Withstand 0.5A Reverse

Current

• Input: Will Withstand Negative Inputs Up to 5V

• ESD Protected: 4 kV

The TC4426AM/TC4427AM/TC4428AM MOSFET

drivers can easily charge/discharge 1000 pF gate

capacitances in under 30 ns, 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.

• Pin-compatible with the

TC426M/TC427M/TC428M and

TC4426M/TC4427M/TC4428M

• Wide Operating Temperature Range:

- -55°C to +125°C

Package Types

• See TC4426A/TC4427A/TC4428A Data Sheet
