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. This particular version (NQFP version) includes a programmable power level of up to 6 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).
NCN5150主要特性:
• Single-chip MBUS Transceiver
• UART Communication Speeds Up to 38,400 baud
• Integrated 3.3 V VDD LDO Regulator with Extended Peak Current Capability of 15 mA
• Supports Powering Slave Device from the Bus or from External Power Supply
• Adjustable I/O Levels..
