Now available, and the first of their kind for space and satellite applications, Cobham's highly-integrated smart power switch controllers.
ARLINGTON, Virginia — Cobham Advanced Electronic Solutions (CAES), announced today the availability of new highly-integrated smart power switch controllers, the first of their kind for space and satellite applications. The UT36PFD103 and UT05PFD103 Smart Power Switch Controllers (SPSC) provide extensive fault detection, isolation, and recovery capabilities as well as digitized telemetry of input voltage, output voltage, and load current into a single device. In addition, Cobham’s new controllers feature PMBus™ protocol over I2C communication, thereby enabling significantly reduced size, weight, power and cost benefits, often yielding better than 75% area and 50% cost reduction over equivalent discrete implementations. With the availability of Cobham’s UT36PFD103 and UT05PFD103 Smart Power Switch Controllers, developers can easily design 4.5V through 36V spacecraft power distribution systems, with the assurance that no load fault will cause undo harm to the bus and associated electronics.
“Cobham has a long heritage as a leader in space and satellite technologies, having powered hundreds of missions over the past 30+ years. Our broad portfolio of semiconductors, radiation hardened, high reliability microelectronic products and IP solutions are recognized worldwide for their pedigree, performance and dependability,” said Kevin Jackson, Vice President and General Manager, Semiconductor and Space Solutions, Cobham Advanced Electronic Solutions. “As the latest addition to our product portfolio and the first of its kind for space and satellite applications, our new Smart Power Switch Controllers continue to offer unparalleled features, integration and functionality, making them the most exemplary intelligent power switch controlling solutions in the market today.”
About the UT36PFD103 and UT05PFD103 Smart Power Switch Controllers
Cobham’s UT36PFD103 (Support for 8V to 36V) and UT05PDF103 (Support for 4.5V to 5.5V) are highly-integrated, power switch controllers with ultra-fast short circuit protection with less than 500ns fault detection to isolation response. The devices agnostically control P-channel Power MOSFET switching elements, making them suitable for switching 4.5V to 36V power of any current class. They also provide an elegant power switching solution for SpaceVPX PowerUM, Pyro Arm-Fire, Long Power Harness Splicing, and Waveguide Actuators. With an integrated PMBus™ serial communication protocol, the UT36/05PFD103 controllers significantly reduce power system size and weight by enabling the use of a low pin-count power system controller (i.e. microcontroller) to configure, command, control, and gather telemetry from every power switch in the system using the I2C serial communication bus. The devices’ fault detection and isolation speed performance alone, makes the UT36PFD103 and UT05PFD103 compelling solutions to protect satellite power buses from short circuit conditions on the output channels of a power distribution unit. Combined with their wide power bus switching range, current class independent operation, and elegant PMBus™ interfacing to the power system controller, the UT36PFD103/UT05PFD103 are ideal intelligent power switch controlling solutions for space and satellite applications. Evaluation Boards and engineering samples are available now. Prototypes will be available in early 2020 and flight units later in the year.
