POWER MANAGEMENT SYSTEM FOR A BUS INTERFACE SYSTEM

摘要

Embodiments of bus interface systems are disclosed. In one embodiment, a bus interface system includes a master bus controller and a slave bus controller coupled along a bus line. The master bus controller is configured to generate an input data signal that is received by the slave bus controller along the bus line. The slave bus controller includes power conversion circuitry configured to convert the input data signal from the master bus controller into a supply voltage. By providing the power conversion circuitry, the slave bus controller is powered using the input data signal and without requiring an additional bus line to transfer a supply voltage to the slave bus controller.
