The (50) OT_FAULT_RESPONSE command instructs the device on what action to take in response to an overtemperature fault. Upon triggering the overtemperature fault, the device responds per the RESTART bit in this register, and sets the OTF_PROG bit in the (7Dh) STATUS_TEMPERATURE register. Due to the lack of an I2C alert pin, the device does not have a way to notify the host.
Return to Supported I2C and Default Values.
