BQ40Z50-R2: BQ40Z50-R3版本休眠退出问题

Part Number: BQ40Z50-R2
Other Parts Discussed in Thread: BQ40Z50-R1

BQ40Z50-R3版本,正常功耗380ua左右,断开通讯后,延迟进入休眠没问题,休眠电流约100uA,正常,但是延时2S后自己瞬间退出休眠,又进入休眠,延时2s又瞬间退出如此反复。Bus Timeout /Voltage Time/Current Time 时间默认设的是5S都改成10s现象还是一样,检流电阻是2毫欧的,Wake Comparator项WK1和WK0置1,为 ±5 mV,还是一点没有改善,不知道是什么原因造成退出休眠问题,按设置应该是休眠后5S唤醒一次检查电压,电流,附件GG文件2S-GG.zip
