CAES introduces its radiation-hardened power switch controller for space applications

05 February 2023

Virginia-based CAES has introduced its Smart Power Switch Controller (SPSC) for power electronics designs in high-reliability space applications.

According to its developers, the SPSC provides fault detection, isolation and recovery capabilities in one package. The radiation-hardened device features space assurance, a wide temperature range, and quick fault detection and recovery in one device.

Further, the SPSC device offers Power Management Bus (PMBus), which communicates over an I2C serial bus. This two-wire command, configuration and control protocol can reportedly manage dozens of power switch channels with a small host controller.

Likewise, the device is also a power bus protection device capable of detecting high- and short-circuit faults and isolating the circuit in 250 nanoseconds.

CAES’s radiation-hardened design meets high-reliability mission profiles and can withstand harsh environments, including QML-Q and QML-V for military and space-grade qualification.
