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
