BQ25730: turn on HIDRV1, HIDRV2 and not(BATDRV) to discharge battery over VBUS

Genius 16285 points
Part Number: BQ25730

Hi all

My customer is using the BQ25730 battery charger and they have a production flow scenario where it would be helpful if they could discharge the battery over the DC-jack (=VBUS).

Here they would need to turn on the external FETs HIDRV1, HIDRV2 and not(BATDRV).

This seems to be not possible using the registers as documented in the datasheet.

Are there undocumented register settings that would allow implementing the above function ?

Best regards
