NCN5150DG Datasheet PDF - ON Semiconductor

●The NCN5150DG 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 38400 baud (half-duplex).

● Single-chip MBUS transceiver

● UART communication speeds up to 38400baud

● Supports powering slave device from the bus or from external power supply

● Adjustable I/O levels

● Low bus voltage operation

● Polarity independent

● Power-fail function

● Fast start-up - no external transistor required on STC pin
