BQ24610 BATFET在电池充满电后的状态和TTC引脚设置问题

Other Parts Discussed in Thread: BQ24610

BQ24610 的BATFET在电池充电时时打开的,那么在电池充满电后的状态时什么样的?

另外TTC那个脚时用来设置定时器和终止控制的,,,不明白定时器和终止时用在哪里,这个脚的设置会影响芯片的什么功能,可以解答一下吗?

        见datasheet描述:

        The device will terminate charging when the termination current threshold has been reached and will begin a recharge cycle when the battery voltage has dropped below the recharge threshold (VRECHG).

        当充电电流小于the termination current threshold, 充电就会停止。(BATFET关闭)

       As a safety backup, the bq2461x also provides a programmable charge timer. The charge time is programmed by the capacitor connected between the TTC pin and GND,

        定时器的作用在于安全方面,例如你设置3小时充电,那么3小时候后自动停止充电。防止一些电池异常造成的安全问题之类。
