POWER DISTRIBUTION MODULE

摘要

A power distribution module (200) is especially suited to vehicular applications. An input/output module port (229) is adapted forconnection to an external multiplexed communication path, with transceiver circuitry (228) being operative to sent and receive messages over the communication path in digital form. The module is flexible enough to support a standard or user-defined communication protocol. An input (231) is adapted for connection to a source of power. A plurality of controllable power switches (240) are used to selectively route power from the source to a plurality of power output ports (251) each port being associated with one of the switches. Control circuitry (220), operatively connected to the transceiver circuitry and to each power switch, facilitates the sending and receiving of messages over the communication path and provides control signals (246) to the switches in accordance with a message received.
