BQ76952: BQ77216拉低 BQ76952 CHG输出的使用问题

您好，this configuration pulls down the CHG gate to GND. This is why the image you shared also shows DOUT and COUT being connected to DFETOFF and CFETOFF respectively. This ensures that the BQ779216 turns off the FET drivers of the BQ76952 and avoid discharging the charge-pump.

The pull-down resistance must be chosen to not draw too much current from the battery.

If they wanted to pull down the gate without using the DFETOFF/CFETOFF pins, then they would likely need additional circuitry to ensure the BQ76952 charge pump does not become discharged.
