Abstract:
1. A method of reducing the amount of power consumed by a galvanic isolator, comprising: transmitting a wake-up signal across an isolation medium from a transmitter when the transmitter is ready or preparing to transmit data or power signals to a receiver operably connected to a sensing circuit; receiving, with the sensing circuit, the wake-up signal through the isolation medium; in response to the sensing circuit receiving the wake-up signal, powering the receiver up from a sleep mode to an operating mode; after a period of time t verifying, with the sensing circuit or the receiver, the validity of the signature pattern and, if the signature pattern is determined to be valid, enabling the receiver to receive the data or power signals; transmitting the data or power signals from the transmitter through the isolation medium, and receiving, with the receiver, the data or power signals.
