BQ25713: 有没有寄存器设置可以关断控制电池充电的那个pmos

Part Number: BQ25713

当电源下线,负载关闭后,只有主控单片机在开着,还是会消耗电池电量,如何控制bq25713的batdrv引脚关断pmos,不给单片机供电,可以保护电池。不想再增加pmos/

  • 您好,没有找到寄存器设置可以关闭BATMOS,请参考数据手册BATDRV的描述,It is shorted to VSYS to turn off the BATFET. It goes 10 V below VSYS to fully turn on BATFET. BATFET is in linear mode to regulate VSYS at minimum system voltage when battery is depleted. BATFET is fully on during fast charge and works as an ideal-diode in supplement mode
