Temperature Data Format
Temperature data can be read from the Temperature Reading Register (address 27h). Temperature limits can be
read from and written to the Hot Temperature, Hot Temperature Hysteresis, OS Temperature, and OS
Temperature Hysteresis Limit Registers (addresses 38h - 3Bh). These limits are also referred to as T
hot
, T
hot hyst
,
T
os
, and T
os hyst
respectively. Each limit is represented by an 8-bit, two's complement word with an LSb (Least
Significant Bit) equal to 1°C:
Temperature Digital Output

+125°C 0111 1101 7Dh
+25°C 0001 1001 19h
+1.0°C 0000 0001 01h

−1.0°C 1111 1111 FFh
−25°C 1110 0111 E7h
−55°C 1100 1001 C9h
By default, Temperature Reading Register is represented by a 9-bit two's complement digital word with the LSb
having a resolution of 0.5°C:
