Product Description
MS721 is a single chip transceiver developed for Meter
Bus standard (EN1434-3) applications.
The MS721 interface circuit adjusts the different
potentials between a slave system and the Meter- Bus
master. The connection to the bus is polarity independent
and supports full galvanic slave isolation with optocouplers.
The circuit is supplied by the master via the bus.
Therefore, this circuit offers no additional load for the slave
battery. A power-fail function is integrated.
The receiver has dynamic level recognition, and the
transmitter has a programmable current sink.
A 3.3-V voltage regulator, with power reserve for a
delayed switch off at bus fault, is integrated
