The OT_FAULT_LIMIT command sets the temperature of the unit, at which, it indicates an overtemperature fault condition. The unit of this command is degrees Celsius. This feature utilizes a digital comparator that compares the output of the IC TEMPERATURE telemetry to the fault threshold selected in this register.
The device response to an overtemperature event is described in (50h) OT_FAULT_RESPONSE.
