BQ76940: Day drive below 3 v

smash Micheal

Part Number: BQ76940

Hi all,

Am facing issue with Dsg drive at voltage lesser than 3 v per cell. Charge Drive stays on but discharge drive disappears, can any help to identify cause?

Hi Rohit,

What are your register settings - specifically the UV_TRIP setting? If there is an under-voltage protection triggered, the DSG FET should turn off to prevent draining the cells further.

Best regards,

Matt
