Hello,

The BQ25756 does not have a shipping mode. You might be able to create a similar functionality with external circuitry. There is no BATFET for the BQ25756 to disable in typical applications since the device is designed to have no power path.

Best,
Michael

Hi,

The BQ25750 has a FORCE_BATFET_OFF bit that will disable the BATFET (bit 4 of REG0x19). The datasheet lists a typical shutdown current of 10 µA under this condition.

Best,
Michael
