3.5.2 Battery Temperature Measurement
The BDATA node, the constant current source, feed the battery data output while monitoring the voltage at
the battery data node with GPADC. This battery data is converted to the battery temperature. (Fig.3-5-5)
shows the schematic of battery temperature measurement part.
