PRODUCTION DATA.
The OT_FAULT_LIMIT command sets the value of the temperature, in degrees Celsius, that causes an overtemperature fault condition, when the sensed temperature from the internal sensor exceeds this limit.
The OT_FAULT_LIMIT must always be greater than the OT_WARN_LIMIT. Writing a value to OT_FAULT_LIMIT less than or equal to OT_WARN_LIMIT causes the device to set the CML bit in the STATUS_BYTE and the invalid data (ivd) bit in the STATUS_CML registers as well as asserts the SMBALERT signal. The contents of this register can be stored to nonvolatile memory using the STORE_DEFAULT_ALL command.
The OT_FAULT_LIMIT takes a two byte data word formatted as shown below.
