Part Number: BQ24296M

Dear Sir,

I found some issue that cannot quit shipping mode.

Here is the description.

1. After entering and exiting the transportation mode many times, it will happen that the shipping mode cannot be exited.

2. plug DC input(12V), but cannot quit shipping mode

3. measured SYS pin and found 0V on this pin(nor. is 4.1V)

4. measured REGN pin and found 0V on this pin(nor. is 5V)

5. remove discharged battery while DC input plugged, REGN pin still 0V.

6. unplug DC input then attached back the discharged battery, and input DC power again, the system quit shipping mode and back to normal.

May I ask, is this situation normal or not?

Why the battery present or not will cause the shipping mode abnormal?
