Overview
MS726 is a monolithic transceiver circuit developed for the application of M-Bus standard (EN1434-3). The MS726 interface circuit can adapt to the voltage difference between the slave station and the master station, the connection of the bus has no polarity requirements, the circuit is powered by the master station through the bus, and the slave battery will not increase additional load. As the receiver, built-in dynamic level identification circuit, integrated 5.5V and 3.3V DC voltage regulator source.
Compared with the MS721, the MS726 has a smaller package size (SOP8/PP), simpler peripheral circuit (8 pins), and integrated 5.5V and 3.3V voltage source, which has a larger output capacity.
