BQ25895M: 寄存器充电模式一直跳变,电池无法充满

Part Number: BQ25895M

电池充一晚上都不不满电,不满足电池截止电压.查看寄存器发现充电模式一直在跳变.

电池电压要大于4.172V,电流要小于64mA才会结束充电.

电压始终不满足大于4.176V,一直停留在4.164V

  • 您好, REG0B = 7E, which indicates charge is terminated. Therefore, it is expected that BQ25895M is no longer charging the battery and voltage is not increasing.  For this case the battery is likely hitting 4.17V threshold, then when charge stops the battery voltage is relaxing a small amount.
