Hi,
Please let me ask the internal passive switch in HD3SS3212. I believe that it has no charge pump and so it's Pch FET based switch. Is my understanding correct? In this case, I understand that the gate of switch is driven low to turn it on, then how does it keep to turn on at low level input signal that can't be ensured Vgs(th) ?
Please share any document such app note that describe such basic information about the operation of USB switch.
Best Regards,
