1. A communication device comprising:
- voice data and RF integrated circuit (IC) that generates a power mode signal based on a selected one of a plurality of power modes, the voice data and RFIC including a RF transceiver circuit and a baseband processing circuit;
an off-chip inductive power circuit that generates an inductive power signal;
an off-chip power management circuit, coupled to the voice data and RF IC and the off-chip inductive power circuit and at least one alternative power source, wherein the off-chip power management circuit;
receives the power mode signal;
generates a power supply signal from one of, the inductive power signal and the at least one alternative power source; and
adjusts the power supply signal in response to the power mode signal.

Abstract
A power status signal is received in an integrated circuit that indicates an inductive power status of an off-chip inductive power module and a battery power status of a battery. A power mode is selected based on the at least one power status signal. A power mode signal is generated based on the selected power mode. A power supply signal is generated and adjusted in response to the power mode signal.

10. A voice data and RF integrated circuit (IC) comprising:
-
a processing circuit that executes a plurality of operational instructions of at least one application and that determines a selected one of the plurality of power modes, and generates a power mode signal based on the selected one of the plurality of power modes; and an on-chip power management circuit, coupled to the processing circuit, an off-chip inductive power circuit and coupleable to at least one alternative power source, that receives the power mode signal and that generates a power supply signal, based on the power mode signal, from one of, a inductive power signal from the off-chip inductive power circuit, and an alternative power signal from the at least one alternative power source; wherein an interface circuit can be selectively deactivated by the processing circuit and wherein the processing circuit generates the power mode signal that commands the on-chip power management circuit to discontinue the generation of a supply voltage to power the interface circuit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
