13.19.2 Fault Handling Sequence

When a Fault occurs, the following steps will occur in sequence.

  1. The gate drive outputs will be immediately turned off.
  2. The FAULT pin output will go low.
  3. A message will be sent via the DE2 communications link if, and only if, the Fault is not a HVDD Overvoltage Shutdown (OVSHDNACT).
  4. The VREG LDO will be disabled immediately if the Fault is a HVDD Overvoltage Shutdown (OVSHDNACT) or a HVDD Undervoltage Shutdown (UVSHDNACT) Fault.
  5. The VREG LDO will be disabled 5 ms after the DE2 message has been sent for an Overtemperature Shutdown (OTSHDN) Fault.
