Hi Mark,

I recommend watching this video on creating the schematic for the BQ76920: https://training.ti.com/how-create-schematic-bq76920-bq76930-and-bq76940

I notice the ALERT, SCL, SDA are all not connected and this will not work. The BQ76920 requires a microcontroller and cannot be used stand-alone. The DSG pin should have a resistor between the pin and the FET gate. I think the video will help to walk you through the requirements.

Best regards,

Matt

Hi Mark,

Sorry about that. An updated revision is publishing and it has not shown up on ti.com yet for some reason. I am attaching the datasheet.
