Radiation Hardened 9A, Non-Inverting Power

MOSFET Drivers

ISL74422ARH

The Radiation Hardened ISL74422ARH is a non-inverting,

monolithic high-speed MOSFET driver designed to

convert a CMOS level input signal into a high current

output at voltages up to 18V. Its fast rise times and high

current output allow very quick control of even the

largest power MOSFETs in high frequency applications.

The input of the ISL74422ARH can be directly driven by

our HS-1825ARH and IS-1845ASRH PWM devices. The

9A high current output minimizes power losses in

MOSFETs by rapidly charging and discharging high gate

capacitances.

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 5962-01521. A link
