Description

The radiation hardened ISL74422BRH is a non-inverting,  monolithic high-speed MOSFET driver designed to convert  5V CMOS logic input signal into a high current output at  voltages up to 18V. Its fast rise/fall times and high current  output allow very quick control of even the largest power  MOSFETs in high frequency applications.

The input of the ISL74422BRH can be directly driven by ou IS-1825ASRH and IS-1845ASRH PWM devices. The 9A  high current output minimizes power losses in MOSFETs b rapidly charging and discharging large gate capacitances. A supply UVLO (Under Voltage Lock Out) circuit insures  predictable turn-on and turn-off of the driver.

Constructed with the Intersil dielectrically isolated Rad-Hard Silicon Gate (RSG) BiCMOS process, these devices ISL74422BRH 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 ISL74422BRH are controlled by the Defense Supply Center in Columbus (DSCC). Th SMD numbers listed here must be used when ordering.
