bq24195 / Input fault flag

Hi Everyone,

Please let me confirm the condition to be set Input fault flag.

My understanding is;

- VBUS rise over OVP threshold

- VBUS goes down below 3.8V at VBAT < 3.8V

However, our customer asked that they unplugged VBUS during charging battery that has over 4.0V and then they confirmed input fault flag.

Please give your comments if this is correct operation or not.

Basically if the input power is not in the good range, one will get a fault.

Since VBUS was removed and the input voltage fell below 3.8V, the input fault flag was set.
