Zusammenfassung:Interface circuit. Example interface circuits may be used for data transfer in accordance with the USB protocol version 3.2 or higher. Example interface circuits are configured to enable cooperation with a sink device and/or a host device having a lower supply voltage than the interface circuit, and reducing or preventing voltage spikes herein after power-on reset (POR) events. Thereto, the detection circuit for detection of a sink device downstream of the interface circuit is provided with a signal path for use during a first period after the POR event and having a resistance larger than a resistance used during detection of the said sink device.
