Abstract
A single-wire interface communication system is capable of providing both electrical communication of signals and power between devices coupled to the system. Coupled to the single-wire interface is at least one target device which contains a PMOS transistor, a charge storage device, an inverter controlling the PMOS transistor, and a target device function. The charge storage device provides power to the target device function and to the inverter. The PMOS transistor receives power from the single-wire interface at a power-supply voltage level and charges the charge storage device to the same level. Non-communication periods produce a charging period sufficient for the charge storage device to attain the power-supply voltage level.
