Radiation Hardened Dual, Non-Inverting
Power MOSFET Drivers
The Radiation Hardened HS-4424RH and HS-4424BRH are
non-inverting, dual, monolithic high-speed MOSFET drivers
designed to convert TTL level signals into high current
outputs at voltages up to 18V.
The inputs of these devices are TTL compatible and can be
directly driven by our 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, like our Rad Hard
FS055, 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
lock-out circuit that puts the outputs into a three-state mode
when the supply voltage drops below 10V for the
HS-4424RH and 7.5V for the HS-4424BRH.
Constructed with the Intersil dielectrically isolated Rad Hard
Silicon Gate (RSG) BiCMOS process, these devices are
immune to Single Event Latch-up and have been speci鏗乧ally
designed to provide highly reliable performance in harsh
radiation environments.
Speci鏗乧ations for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Speci鏗乧ations for these devices are
