Hi team,
Could you please further explain the function of PMID? I don't why this pin is designed to connect RBFET and HSFET. It is a Digital output but connected to a capacitor?

Hi Ning,
Thanks for your reply. Could you please give me more detail? Did you mean that the PMID pin could be used to supply other socket?
Hi,
When valid VBUS is applied. Q1 (RBFET) turns on, so PMID is short to VBUS generally. That's why PMID is also the power input for the charger.
Thanks,
Ning.
Hi,
Why need to set a PIN specifically to display the value of the input voltage?
Thanks!
Hi,
Although both VBUS and PMID are the input to the charger, the RBFET (reverse-blocking FET) in between helps to prevent the current flowing from the load side to the input supply side (i.e. VBUS adaptor). This is explained in the e2e link below.
Thanks,
Ning.
