The UT05PFD103 Smart Power Switch Controller is the space industry's first highly integrated power switch controller providing extensive fault detection, isolation, and recovery capabilities combined with built-in digitized telemetry of input voltage, output voltage, and load current.

The UT05PFD103 is an intelligent PowerMOSFET controller with load-side inrush current limiting and 4.5V – 5.5V eFUSE protection of current faults.Combining adjustable current and voltage monitoring capability with flexible fault detection, isolation and recovery, the Smart Power Switch Controller integrates many of the critical functions required for power switching applications and often implemented with a number of discrete components.

The UT05PFD103, Smart Power Switch Controller Evaluation Board, SPSC-EVB, provides users with a convenient and flexible platform from which to evaluate the manifold features and functions available with the UT05PFD103.

The SPSC-EVB may be operated in single-supply stand-alone form (i.e. without host microcontroller) and in full-featured operation when installed as an ARDUINO shield onto a compatible host microcontroller evaluation board. To facilitate rapid evaluation, Frontgrade provides a software API for the UT32M0R500 Arm M0+ evaluation board to service the Smart Power Switch Controller along with a run-time executable graphical user’s interface (GUI).
