M-Bus

The BL15721B is a single chip transceiver developed for Meter-Bus standard (EN1434-3) applications.The BL15721B interface circuit adjusts the different potentials between a slave system and the Meter-Bus master. The receiver has dynamic level recognition, and the transmitter has a programmable current sink. The circuit is supplied by the master via the bus. Therefore, this circuit offers no additional load for the slave battery.
