PRODUCTION DATA.
The OT_FAULT_RESPONSE command instructs the device on what action to take in response to an OT_FAULT_LIMIT. The device also:
When the overtemperature fault is tripped, the fault flag is latched until the internal sensed temperature decreases 20°C from the OT_FAULT_LIMIT.
The contents of this register can be stored to nonvolatile memory using the STORE_DEFAULT_ALL command.
The default response to an over temperature fault is to ignore. Fixed Bandgap Detected Overtemperature faults are never ignored. The Bandgap OT faults always respond in a shutdown and attempted restart once the part cools.
