亲们,我在使用BQ25890过程中发现ADC采样仅在充电时有效,放电时BQ25890的ADC采样无效吗,我读不到我的电池电压
Johnsin Tao:
HiThe device also provides a 7-bit analog-to-digital converter (ADC) for monitoring charge current and
input/battery/system (VBUS, BAT, SYS, TS) voltages. The QON pin provides BATFET enable/reset control to
exit low power ship mode or full system reset function从描述看,可以读充电电流(不能读放电电流),可以读电池电压(没有强调一定是充电时)
