ABSTRACT:
An apparatus for identifying the identity of an accessory device connected to an electronic device using a voltage divider circuit, an analog to digital converter, and a database associating various digital values with the identity of various accessory devices. The voltage divider circuit includes a first resistor located within the electronic device and having a single resistance value. The voltage divider circuit also includes a second resistor located within the accessory device whose resistance value varies between accessories such that a distinct voltage value is applied to the analog to digital converter for each accessory. The digital output value of the analog to digital converter is compared with a list of values stored within the database to determine the identity of the accessory device.
