Abstract
In an embodiment, set forth by way of example and not limitation, a USB dedicated charger identification circuit includes a USB D+ port, a USB D− port, a first circuit conforming to a first identification protocol, a second circuit conforming to a second identification protocol, and logic selectively coupling one of the first circuit and the second circuit to the USB D+ port and the USB D− port. In an alternate embodiment set forth by way of example and not limitation, a method to provide USB charger identification includes providing a first USB charger identification at a USB D+ port and a D− port, Next, it is detected if the first USB charger identification was inappropriate. Then, if the first USB charger identification was inappropriate, a second USB charger identification is provided at the USB D+ port and the D− port.
