Preliminary Technical Data
T
The T
the temperature hysteresis value for the T
temperature limits. The temperature hysteresis value is stored in
straight binary format using four LSBs. Increments are possible
in steps of 1°C from 0°C to 15°C. The value in this register is
subtracted from the T

T
The 16-bit T
the overtemperature limit value. An overtemperature event occurs
when the temperature value stored in the temperature value
register exceeds the value stored in this register. The INT pin is
activated if an overtemperature event occurs. The temperature
is stored in twos complement format with the most significant
bit being the temperature sign bit.

T
The 16-bit T
the undertemperature limit value. An undertemperature event
occurs when the temperature value stored in the temperature
value register is less than the value stored in this register. The
INT pin is activated if an undertemperature event occurs. The
temperature is stored in twos complement format with the MSB
being the temperature sign bit.
