BQ24725AEVM-710: BQ24725A如何提示充满

您好，请教一下，，像ACOK引脚可以知道，是否插入适配器，BQ24725A如何知道电池已经充满呢

Star Xu：

您好，This family of chargers is host-controlled. The host MCU must write to the ChargeVoltage() and ChargeCurrent() registers and control the charge profile as desired. There is no built-in termination current setting. On their own, these chargers will taper the charge current all the way down to zero in CV (constant voltage) mode. This is mainly due to legacy notebook battery charger design practices, in which the gauge will control the charge termination.

谢谢，我需要通过IOUT来检测充电电流，如充电电流逐渐为0时，则认为充电截止，主动关闭充电吗

Star Xu：

您好，这款芯片没有截止通电电流，一般是通过电量计芯片控制充电截止。
