BQ40Z50-R1 sleep 问题

Other Parts Discussed in Thread: BQ40Z50-R1, EV2400, BQ40Z50-R2

TI工程师您好!

我现在按照Technical Reference的sleep条件设置了BQ40Z50-R1 的sheep mode,我的设置如下:

也满足一下条件

将通讯拔掉,即满足no communication 的条件。过几秒再次接上ev2400后,发现fuse置位,CHG和DSG关闭。重复以上操作仍然出现该现象。fuse pin 已经接100R电阻对地,且已关闭fuse_en。发送reset后,恢复正常,fuse清零,且CHG和DSG正常打开。

请问我如何设置sleep mode(现在在normal  mode 下电流为300多uA),为什么会出现fuse 置位的现象呢?软件设置还是硬件设置问题?
