8.4.3 AM Faults and INTB Output

AM faults are:

  • Port under and overvoltage faults
  • Overcurrent faults
  • Undercurrent (DC Disconnect) fault
  • Thermal shutdown (TSD) fault
  • Watchdog timer faults (disabled through WD_DIS pin)

Any one of the first four fault conditions listed above causes the port to shut down, and a 3-bit fault code to be latched into the affected port's Status Read 1 register (addr = 0100b). Watchdog faults cause all four ports to shut down. Faulted ports are temporarily disabled after a fault has been detected and latched.

The INTB pin is an open-drain, active-low output which is asserted if a fault condition occurs on any of the four ports. This indication is asserted for any of the port faults which result in a code displayed in the port status register (the faults listed in Table 8-8). In auto mode, the fault latch, the status register fault bits, and consequently, INTB assertion, are cleared by expiration of the 750-ms TED timer.
