BQ27421-G1: Can we include battery detection using bq27421-G1 fuel gauge

Part Number: BQ27421-G1

Hello,

We have a basic query regarding bq27421-G1(fuel gauge)

In my product two power options

1. Wall adapter

2. Li-Ion Battery

Customer have requirement that,

when we remove the battery we can analyse and detect the board is working from main supply(Wall adapter)

When the main supply is off we need to detect the board is working from battery.

Kindly update us if there a way to detect this requirement from fuel gauge.

Regards,

Alwin
