Current
The bq28400 uses the SRP and SRN inputs to measure and calculate the battery charge and discharge current
using a 5-mΩ to 20-mΩ typical sense resistor.
Temperature
The bq28400 has an internal temperature sensor and input pin for an external temperature sensor. The bq28400
can be configured to use either the internal or external temperature sensor. The default setting for the bq28400 is
for a Semitec 103AT thermistor as input to the TS1 pin. Reporting of measured temperature is available by way
of the SBS Temperature command.
