Radiation Hardened 9A, Non-Inverting
Power MOSFET Drivers
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.
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.
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 鈥渉ot-link鈥?is provided
on our homepage for downloading.

NOTES:
1. Pin 3 provides the supply voltage for the control logic. It is not
internally connected to Pins 15 and 16 for noise immunity
purposes, but may be connected externally.
2. Pin 5 is the control logic return. It is not internally connected to
Pins 8 and 9 for noise immunity purposes, but may be connected
externally.
3. Pins 8 and 9 MUST both be connected to GND.
4. Pins 12 and 13 MUST both be connected to the output.
5. Pins 15 and 16 MUST both be connected to VS.
