International Rectifier – Radiation Hardened Non-Inverting Dual Output MOSFET Drivers, RIC74424H (04/2022)

The RIC7442H is part of the International Rectifier HiRel family of products. The RIC74424H is a monolithic, radiation hardened, dual high speed MOSFET driver intended for harsh radiation environments. The driver is designed specifically to drive all of IR’s power MOSFETs where ultra-fast switching speed and fast propagation response time is imperative to boost the circuit efficiency. The driver is compatible with most logic devices and can be driven directly by a standard pulse width modulator such as the industry’s standard 1825, 1844 and 1856 product families. The MOSFET driver is available in an 8 Lead surface-mountable Flat Pack (FP), and in die form. The driver is designed to meet the key radiation requirements without any performance de-rating.
