Abstract
A system for mitigating a solid state power controller (SSPC) open fault caused by single event latchup (SEL) on a power module includes a microprocessor in a control communication and power supply module (CCP) configured to determine whether communication with a microcontroller in at least one of a solid state power controller (SSPC) and a second SSPC in the power module is lost. The microprocessor in the CCP is operatively connected to the power module and configured to notify, via a backplane communication bus, the microcontroller on the power module that the communication with the SSPC in the power module is lost. The microcontroller in the SSPC is configured to set a low power operation of a second SSPC in the power module not affected by SEL in response to loss of reception of command messages from the microprocessor in the CCP.
