BQ40Z50: BQ40Z50 睡眠模式进入和 shutdown

Daniel：

您好

wenguang bi 说：BQ40Z50 进入睡眠模式的条件？

https://www.ti.com/lit/ds/symlink/bq40z50.pdf

根据datasheet说明以下情况

The SMBus clock and data lines have internal pulldown. When the gas gauge senses that both lines are low (such as during removal of the pack), the device performs auto-offset calibration and then goes into SLEEP mode to conserve power.

wenguang bi 说：另外如果进入睡眠模式是否 CHSG fet 和 DSG fet 都关闭？

以下是啊SLEEP mode是IC的情况

In SLEEP mode, the BQ40Z50 performs measurements, calculations, protection decisions, and data updates in adjustable time intervals. Between these intervals, the BQ40Z50 is in a reduced power stage. The BQ40Z50 has a wake function that enables exit from SLEEP mode when current flow or failure is detected.

wenguang bi 说：如果说检测到一个 特定电流比如（-60mA，无通讯）想让电池进入睡眠模式或shutdown 模式 需要怎么操作

您可以通控制器或者是比较器来给第一个回复中两条线拉低来进入SLEEP状态。
