Hi..
I am using Bq76940 for BMS. My Power supplies are ok. I want to check the discharging drive ON. Can we test the Nch FET drive without writing in the register Bits.

Hi Vikas,
The pull down resistance of the DSG and CHG is shown in the data sheet. While the DSG and CHG pins can be shorted low when driven high, I would not recommend pulling DSG high while it is held low with the internal 1k pull down. CHG has a 1M nominal internal pull down, so it could be pulled high.
