Abstract: At least some aspects of the disclosure provide for a system. In at least some examples, the system includes a microcontroller, an energy storage element, a monitoring circuit, and a communication bridge. The monitoring circuit is coupled to the energy storage element and configured to determine whether a fault associated with the energy storage element is present, generate an indication of the fault when the fault with the energy storage element is present, and transmit the indication of the fault. The communication bridge is configured to receive the indication of the fault and assert a fault signal and transmit the fault signal to the microcontroller.
