BQ25703A: BAT short-circuits

GARETH OU

Part Number: BQ25703A

The customer short-circuits BAT+ and GND when verifying charging,
Will the BQ25703A protect it at this time and turn off the charging current?
Which register is the system going to read to know that the BQ25703A has access protection or information that the charging is turned off?

Hi,

It will trigger BAT UVLO and shut off charging.
