Here is the datasheet for the PMIC chip:

The third pin is normally a thermistor temp sensor inside the battery. The datasheet should allow you to verify.
The PMIC can charge the battery. These PMICs are widely used in tablets, phones, etc. All of the AXP PMICs are very similar. The different part numbers are for different numbers of regulators or power on voltages.
