HT71D04 -- Power Line Data Transceiver
General Description
In systems where a master controller controls a number of individual interconnected subsystems such as found in smoke detector systems, water metering systems, solar energy system etc., the cost of the lengthy interconnecting cabling can be a major factor. By sending data along the power supply lines, the interconnecting cables can be reduced to a simple two line type, thus greatly reducing both cable and installation costs.
With a the addition of a few external components, this power line data transceiver device contains all the internal components required to provide users with a system for power line data transmission and reception. Data is modulated onto the power line by the simple reduction of the power line voltage for a specific period of time. Power supply voltage changes can be initiated by the master controller for data reception or initiated by the HT71D0x devices for data transmission. An internal voltage regulator within the device ensures that a constant voltage power supply is provided to the interconnected subsystem units while an internal voltage detector monitors the power line voltage level.
