CAES, a leading provider of mission-critical electronics for aerospace and defense, has launched a new device designed for the harshest space missions. The new Smart Power Switch Controller (SPSC) offers extensive fault detection, isolation, and recovery capabilities (FDIR) in a single package. The radiation-hardened (RadHard) device features the highest level of space assurance, and wide temperature range coverage, and provides quick fault detection and recovery in a small footprint.
“Our SPSC has been designed to meet the toughest requirements demanded in modern space programs. It allows design engineers to eliminate multiple discreet components for superior design functionality and capabilities in a single package,” said Mike Elias, Senior Vice President, Space Systems Division, CAES. “The SPSC provides extensive device protection, with 10 times faster response time compared to existing solutions. We’re excited to bring these capabilities to our customers.”
Our new HiRel SPSCs are intelligent, current class agnostic, and the first in the space industry to incorporate PMBus, which communicates over an I2C serial bus. This simple and flexible 2-wire command, configuration, and control protocol can manage dozens of power switch channels with a small host controller.
The SPSC is also a power bus protection device, with the ability to detect high/short circuit faults and isolate the circuit in 250 nanoseconds. CAES’ RadHard design techniques ensure that our devices - including the Smart Power Switch Controller - meet the highest reliability mission profiles and can withstand the harshest environments, including QML-Q and QML-V for military and space-grade qualification.
