Abstract: This is generally directed to providing protection circuitry to selectively handle power-providing cables and headset cables that can couple to the same port of an electronic device. In some embodiments, the device can include a Headset Rx chip to communicate with the headset cable and a Power Rx chip to communicate with the power-providing cable. As the Headset Rx chip and the Power Rx chip can be coupled to the same contact of the device's port, these chips may prevent one another from operating correctly or may damage one another. Accordingly, in some embodiments, it can be determined whether a headset cable or a power-providing cable is coupled to the device. When a headset cable is coupled to the device, the protection circuitry can disconnect the Power Rx chip. Similarly, when a power-providing cable is coupled to the device, the protection circuitry can disconnect the Headset Rx chip.
