8.6.8 Hysteresis Register (Address = 07h) [reset = 0A0Ah]

This register sets the hysteresis for the THigh_Limit threshold and the TLow_Limit threshold. The default

hysteresis value for both the high and low limits is equal to 5 °C.

The Hysteresis is in a 8-bit unsigned format with the LSB equal to 0.5°C. This gives a maximum value of

127.5°C of hysteresis.

Description

15:8

THigh_Hyst[7:0]

R/W

0Ah

THigh_Limit Hysteresis setting.

Hysteresis value is represented by a unsigned Byte with the

LSB equal to 0.5°C. The High temperature limit hysteresis

threshold is equal to (THigh_Limit - THigh_Hyst).

The default hysteresis value is 5 °C.

7:0

TLow_Hyst[7:0]

R/W

0Ah

TLow_Limit Hysteresis setting.

Hysteresis value is represented by a unsigned Byte with the

LSB equal to 0.5°C. The Low temperature limit hysteresis

threshold is equal to (TLow_Limit + TLow_Hyst).

The default hysteresis value is 5 °C.
