BQ24780S: Behavior at SRP pin left open during fast charging

Part Number:BQ24780S

Hi,

Now the customer examine the abnormal case such as removed external components or pins of IC left open due to mechanical shock or vibration. Then they are asking the behavior at SRP pin left open during fast charging. Can you give your opinion about the behavior in this case?

I guess that the SRP pin voltage goes down below SRN pin after SRP pin left open, and it means that charger think the discharge (reverse current) is started. So I'd like to know the operation at VSRP < VSRN during fast charging.

Your kind response will be appreciated. 

Best Regards,
