BQ24171: Operation of Charging Circuit

Part Number: BQ24171

Tool/software:

We are testing the operation of the charging circuit using BQ24171.
However, a problem has occurred and the cause is under investigation.

The defects are as follows
When +12V is input, voltage is not output and STAT becomes abnormal.
When +5V is input, charging operates without any problem.

I'm sorry, but could you please check if there is a problem with the schematic?
The schematic is attached.

VIN=+12V
VBAT=+4.1V
ISET=2A
Single-Cell Unremovable Battery

Best Regards,

Okashita.
