The VBUS_in_discharge pin has 30V rating, but the bus voltage is 21V maximum.

Is there a specific reason to have such a high voltage rating on this pin?

Thanks

Hi ,

Those SPEC in VBUS_IN_DISCHARGE is benefit for CCGx device. Typically, the VBUS voltage is not over 21 volt, but we need consideration the error or ripple on VBUS voltage control.  Typically, 50% tolerance is best choice.
