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.
