General Description

The TC4426/TC4427/TC4428 are improved versions

of the earlier TC426/TC427/TC428 family of MOSFET

drivers. The TC4426/TC4427/TC4428 devices have

matched rise and fall times when charging and

discharging the gate of a MOSFET.

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

2.0 kV.

The TC4426/TC4427/TC4428 MOSFET drivers can

easily charge/discharge 1000 pF gate capacitances in

under 30 ns. These devices provide low enough

impedances in both the on and off states to ensure the

MOSFET’s intended state is not affected, even by large

transients.

Other compatible drivers are the TC4426A/TC4427A/

TC4428A family of devices. The TC4426A/TC4427A/

TC4428A devices have matched leading and falling

edge input-to-output delay times, in addition to the

matched rise and fall times of the TC4426/TC4427/

TC4428 devices.
