why not ovp protection ?

HW

MSM8917
PM8937
PMI8940

Question :

Recently, I connect usb cable with 10V to the phone.
Why does the phone still charging ? Why it not stop charging ?

Solution :

Because pmi8940 support up to 9V adapter, it's ovp up to 10.3V
You also can set related registers to support only 5V adapter,
it's ovp has two option,
You can refer pmi8940 spec 0x13f1 register
