7.1.1.6 Temperature

The bq3060 has an internal temperature sensor and inputs for 2 external temperature sensor inputs TS1 and TS2 used in conjunction with two identical NTC thermistors (default is Semitec 103AT) to sense the battery cell temperature. The bq3060 can be configured to use internal or up to 2 external temperature sensors.
