• QML Qualified per MIL-PRF-38535 Requirements
• Electrically Screened to DSCC SMD # 5962-01521
The Radiation Hardened ISL4422ARH is a non-inverting,
monolithic high-speed MOSFET driver designed to convert a
5V 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.
• Radiation Environment
- Total Dose (Max) . . . . . . . . . . . . . . . . . . . . 300krad(SI)
- Latch-Up Immune
- Negligible Sensitivity to Low Dose Rates
The input of the ISL4422ARH 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.
