BQ24295: 求助，我的BQ24295无法在只有电池的时候工作

R22没有焊接在主板，TS角被上拉到3.3V

您好，请参考schematic checklist 和 PCB Layout Design Tips

我检查了checklist但并没有发现我的设计有哪里错了导致没有VSYS输出

您好，正在查询，稍后回复。

您好，有结果了吗

您好，请参考下面内容

1)Can you provide a read of all registers after VSYS drops to 0V? Has the BATFET been forced off (this is checked in REG07 bit 5)? 

2)You mention "At the moment the battery is inserted" as part of the test conditions. Is the VSYS = 0V behavior observed in test condition when battery is always connected then device transitions from charging battery to battery powering SYS when USB adapter at VBUS is removed? 

1. I have read the status of REG07. The status of REG07 is as shown below.
2. When the battery is always inserted and the USB power supply is plugged in, the system outputs VSYS normally. But if the adapter is unplugged, VSYS quickly drops to about 0.04V.

您好，正在询问更了解这款芯片的TI工程师，稍后回复。
