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 spik-
ing (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.
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 will not be 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.
