3 A Dual High-Speed
MOSFET Drivers
The NCP4423/4424/4425 are MOSFET drivers that are capable of
giving reliable service in demanding electrical environments.
Although primarily intended for driving power MOSFETs, these
drivers are well–suited for driving other loads (capacitive, resistive,
or inductive) which require a low impedance driver capable of high
peak currents and fast switching times. Applications such as heavily
loaded clock lines, coaxial cables, or piezoelectric transducers can all
be driven with the NCP4423/4424/4425. The only known limitation
on loading is that the total power dissipated of the driver must be kept
within the maximum power dissipation limits of the package.
