MILPITAS, Calif. The first flight of NASA's Orion spacecraft, dubbed uncrewed Exploration Flight Test 1, made use of 16 radiation-hardened (rad-hard) ICs from Intersil Corp.

Intersil's components were used in Orion's crew module, where they support subsystems for mission critical applications in navigation, power distribution, flight control, and inertial measurement unit. Intersil rad-hard products used include comparators, voltage regulators, PWM controllers, multiplexers, dual analog switches, MOSFET drivers, quad differential receivers, and microprocessor supervisory circuits.

The Orion spacecraft's missions will include exploration, collection of asteroid samples from a future planned robotic mission that will redirect an asteroid to orbit the moon, and the a manned mission to Mars.

All Intersil SMD products are MIL-PRF-38535/QML compliant, are 100 percent burned in, and are on individual DLA SMD drawings.
