The TC4423A/TC4424A/TC4425A devices are a family
of dual-output 3A buffers/MOSFET drivers. These
devices are improved versions of the earlier TC4423/
TC4424/TC4425 dual-output 3A driver family. This
improved version features higher peak output current
drive capability, lower shoot-throught current, matched
rise/fall times and propagation delay times. The
TC4423A/TC4424A/TC4425A devices are pincompatible
with the existing TC4423/TC4424/TC4425
family. An 8-pin SOIC package option has been added
to the family. The 8-pin DFN package option offers
increased power dissipation capability for driving
heavier capacitive or resistive loads.
The TC4423A/TC4424A/TC4425A MOSFET drivers
can easily charge and discharge 1800 pF gate
capacitance in under 20 ns, 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.
The TC4423A/TC4424A/TC4425A inputs may be
driven directly from either TTL or CMOS (2.4V to 18V).
In addition, the 300 mV of built-in hysteresis provides
noise immunity and allows the device to be driven from
slow rising or falling waveforms.
The TC4423A/TC4424A/TC4425A dual-output 3A
MOSFET driver family is offerd with a -40oC to +125oC
temperature rating, making it useful in any wide
temperature range application.
