当前将DFETOFF配置关断放电MOS的功能,在DFETOFFPin有效(放电MOS确实关了)每隔30S进入Sleep模式时有时会失败,打开放电MOS就可以正常进入,这里在手册上哪里有具体描述,应如何配置,在Sleep模式下仅关放电MOS?

您好,You are correct, disabling the discharge FET with the DFETOFF pin does prevent the device from going into SLEEP mode. If you disable the DSG FET with the DSG_PDSG_OFF() command, it will not prevent SLEEP mode, so this might be a better option for you.
