HS-4424RH, HS-4424BRH

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 specifically

designed to provide highly reliable performance in harsh

radiation environments.

Specifications 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 Specifications for these devices are

contained in SMD 5962-99560. A “hot-link” is provided
