Overview

The NCN5150 is a single-chip integrated slave transceiver for use in two-wire Meter Bus (M-BUS) slave devices and repeaters. The transceiver provides all of the functions needed to satisfy the European Standards EN 13757-2 and EN 1434-3 describing the physical layer requirements for M-BUS. It includes a programmable power level of up to 2 (SOIC version) or 6 (NQFP version) unit loads which are available for use in external circuits through a 3.3V LDO regulator.
The NCN5150 can provide communication up to the maximum M-BUS communication speed of 38400 baud (half-duplex).
