TEMPERATURE (°C)
(Note
6.1)
The temperature measurement range is from 0°C to +191°C. The data format can be selected between
pure 2’s complement format which displays data from 0°C to +127°C, or in offset 2’s complement
format that displays data over the entire data range. The temperature format is shown below:
Note 6.1
If the High Side Fan Driver is active, then self-heating of the large current drive device will affect the
internal temperature reading. Therefore, it is not recommended that the Internal temperature channel
be used to monitor the ambient air temperature.
