Embodiments herein relate to an electronic device that includes a system-on-chip (SoC). The electronic device may further include a USB port to provide a first identification signal that is at a first voltage and that is related to a charging process between a USB device to which the USB port is coupled an the electronic device. The electronic device may further include a power delivery (PD) controller to: generate, based on the first identification signal, a second identification signal at a second voltage that is lower than the first voltage; and provide the second identification signal to the SoC. Other embodiments may be described and claimed.
