Abstract
A system that includes a bus, a battery, core processing circuitry, radio frequency (RF) processing circuitry, first power regulating circuitry, second power regulating circuitry, and control circuitry is provided. The bus can be coupled to receive power from a source external to the system. The core processing circuitry and RF processing circuitry can be selectively coupled to each other via a switch. The switch can be operative to turn ON and OFF based on a signal level received on the bus. The first power regulating circuitry can be electrically coupled to the bus, the core processing circuitry, and the switch. The second power regulating circuitry can be electrically coupled to the battery, the RF processing circuitry, and the switch. The control circuitry can be operative to selectively turn ON and OFF the first power regulating circuitry and the second power regulating circuitry based on a number of monitored conditions.
