使用BQ24170,不接外部电源,电池使用一段时间,当接外部电源时,电池电量用掉多少时候会充电。
还是不管剩余多少,接了外部电源就把电池电量充到100%?

你好。单节电池电压下降100mV、2节电池电压下降200mV、3节电池电压下降300mV就会复充。见规格书 Recharge Threshold.
A new charge cycle is initiated when one of the following conditions occurs:
• The battery voltage falls below the recharge threshold
• A power-on-reset (POR) event occurs
• ISET pin toggled below 40 mV (disable charge) and above 120 mV (enable charge)
Hi
这个不是按照百分比来判定的,而是按照如上门槛值来判定的。
你好,
Rsense电阻换成40毫欧,ICHG为原来的一半,这个是指0.6A还是1A呢?另外,请检查一下ACSET引脚上的电压,可能是进入IinDPM状态,限制了充电电流。
