NCN5150: Wired M-BUS Slave Transceiver

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).

Features
  • Single-chip MBUS Transceiver
  • UART Communication Speeds Up to 38400 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
  • Adjustable Constant Current Sink up to 2 or 6 Unit Loads Depending on the Package
  • Low Bus Voltage Operation
  • Extended Current Budget for External Circuits: at least 0.88 mA
  • Polarity Independent
  • Power-Fail Function
  • Fast Startup - No External Transistor Required on STC Pin
  • Industrial Ambient Temperature Range of -40C to +85C
  • Available in: - 16-pin SOIC (Pin-to-pin compatible with TSS721A)- 20-pin QFN
  • These are Pb-Free Devices
Applications
  • Multi-Energy Utility meters- Water- Gas- Electricity- Heating systems
