Abstract

Circuitry in an adapter, such as a power supply, can provide power at a desired voltage level to a portable device. The circuitry may assert one of several electrical configurations on the cabling that electrically connects the portable device to the external device to indicate to the external device a desired voltage level.

First claim

We claim the following:

1. An electronic circuit comprising:
a power bus;
a signal bus; and
circuitry connected to the signal bus,
the circuitry being operative to:
detect an electrical configuration from among a plurality of electrical configurations on the signal bus, each of the electrical configurations being associated with a voltage level; and
provide power to the power bus at a voltage level that is substantially equal to the voltage level associated with the elect…
