NCN5150
Wired M-BUS Slave
Transceiver
Description
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 3.3 V LDO
regulator.
The NCN5150 can provide communication up to the maximum
M-BUS communication speed of 38,400 baud (half-duplex).
