BQ25895的BATFET (Q4)是否可以通过QON引脚完全关闭?



  当VBus 不插入供电时,BAT引脚的电池电压总是通过Q4供给到 Sys 引脚,测量到SYS引脚的电压和BAT引脚电压相等,请问为了省电是否可以把BATFET(Q4)通过QON控制脚关掉?

  • 您好, QON的作用请参考数据手册的Pin Functions和8.2.10.3 BATFET Full System Reset
    您可以通过BATFET_DIS bit (REG09[5]) 来控制BTAFET 的开关, 请参考数据手册9.2.10.2 BATFET Enable (Exit Shipping Mode)
