Radiation hardened ICs blast off on Orion's flight test

09-02-2015 | Intersil | Design Applications

Intersil has announced that 16 of its radiation-hardened ICs were onboard
the Dec. 5, 2014 maiden voyage of NASA's Orion spacecraft, also known as the
uncrewed Exploration Flight Test 1. The Orion spacecraft is designed to go
where no man has gone before, including astronauts exploring and collecting
asteroid samples from a future planned robotic mission to redirect an
asteroid to orbit the moon, and the long sought after manned mission to
Mars.

Intersil's rad-hard ICs are deployed in Orion's crew module, where they are
used to support subsystems for mission critical applications in power
distribution, navigation and flight control, and in the inertial measurement
unit. A wide range of Intersil rad-hard solutions are used including voltage
regulators, comparators, multiplexers, PWM controllers, MOSFET drivers, dual
analog switches, quad differential receivers and microprocessor supervisory
circuits, says the company.

"Intersil's innovative rad-hard ICs are playing a key role in NASA's next
big step into deep space exploration, which is energizing a new generation
of engineers, scientists and astronauts," said Philip Chesley, senior vice
president of precision products, Intersil. "The successful Orion test flight
is a major achievement, and we're proud to be a part of it."
