BQ76940: BQ76940 Chg & Discharing drive

Part Number: BQ76940

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.
