Alarm Threshold Registers
Default Value
Serial Address
Byte Address
Each LSB of TMAXh represents one degree centigrade. This register is to be used in conjunction with TMAXl to yield a sixteen-
bit temperature value.
The value in this register is uncalibrated. The nine MSbits of threshold value (TMAXh;TMAXl) are compared bit to bit to the
nine MSbits value of the temperature reading (TEMPh;TEMPl).. Alarm bit Ax is set if Reading > Threshold.
Default Value
Serial Address
Byte Address
Each LSB of TMINh represents one degree centigrade. TMINh is to be used in conjunction with TMINl to yield a sixteen-bit
temperature value. The value in this register is uncalibrated. The nine MSbits of threshold value (TMINh;TMINl) are compared,
bit to bit, to The nine MSbits value of the temperature reading (TEMPh;TEMPl). Alarm bit Ax is set if Reading < Threshold.
Default Value
Serial Address
Bytes Address
Each LSB of VMAXh represents 25.6mV and each LSB of VMAXl represents 0.1mV. The sixteen bits threshold value
(VMAXh;VMAXl) is compared bit to bit to the sixteen bits value of the voltage reading (VINh;VINl). Alarm bit Ax is set if Reading
> Threshold.
