ISL74422BRH ® Data Sheet October 2003 Radiation Hardened, 9A, Non-Inverting Power MOSFET Driver FN6057 Features • QML Qualified per MIL-PRF-38535 Requirements 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 SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-03248.
