bq294582 customer test mode

Other Parts Discussed in Thread: BQ294582

bq294582 having a customer test mode.

Appling more than 10V on VDD over VC3 brings the IC into CTM.

The Datasheet (page 8) desribes the delay timer is reduced to about 10ms.

But in the diagram (page 9) you see that the output is set to high, without any overvoltage event on VC3.

 

Is the overvoltage protection disabled in CTM?

If yes, why?

 What can be tested in this mode?

How this mechanism works ?
