接口 - 专用 NCN5150 SOIC OAC

Wired M-BUS Slave  Transceiver

NCN5150DR2G 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.
