Overview
MS721 is a monolithic transceiver circuit developed for M-Bus standard (EN1434-3) applications. The MS721 interface circuit accommodates the voltage difference between slave and master devices, with no polarity requirement for bus connections. The circuit is powered by the master through the bus, eliminating additional load on the slave battery, while integrating a power failure detection function. When operating as a receiver, it incorporates a built-in dynamic level detection circuit; when operating as a transmitter, it features a built-in programmable current source. A 3.3V DC voltage regulator is integrated, which shuts down after a delay following a bus fault.
Applications
