Apparatus using serial data line to turn on a transceiver or other device |
摘要 |
An apparatus and a method for using a serial data line to turn on an electrical device are disclosed. Energy is extracted from a data signal on an asynchronous serial data line using a charge pump. The extracted energy is used by a power supply switching circuit to turn power on. Once turned on, power is kept on by a keepalive circuit. A shutdown signal causes the power to be turned off.
