DATASHEET
Dual, Noninverting Power MOSFET Radiation Hardened
Drivers
HS-4424DRH, HS4424DEH
The radiation hardened HS-4424 family are noninverting, dual,
monolithic high-speed MOSFET drivers designed to convert low
voltage control input signals into higher voltage, high current
outputs. The
HS-4424DRH, HS-4424DEH
are fully tested
across the 8V to 18V operating range.
The inputs of these devices can be directly driven by the
HS-1825ARH PWM device or by our ACS/ACTS and HCS/HCTS
type logic devices. The fast rise times and high current outputs
allow very quick control of high gate capacitance power
MOSFETs in high frequency applications.
The high current outputs minimize power losses in MOSFETs by
rapidly charging and discharging the gate capacitance. The
output stage incorporates a low voltage lockout circuit that
puts the outputs into a three-state mode when the supply
voltage is below its Undervoltage Lockout (UVLO) threshold
voltage.
Constructed with Intersil’s dielectrically isolated Rad Hard
Silicon Gate (RSG) BiCMOS process, these devices are immune
to single event latch-up and have been specifically designed to
provide highly reliable performance in harsh radiation
environments.
