October 2003 Radiation Hardened, 9A, Non-Inverting Power MOSFET Driver
The radiation hardened ISL74422BRH is a non-inverting,
monolithic high-speed MOSFET driver designed to convert a
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 our
IS-1825ASRH and IS-1845ASRH PWM devices. The 9A
high current output minimizes power losses in MOSFETs by
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 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 …
