描述 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 3.3V LDO regulator. The NCN5150 can provide communication up to the maximum M-BUS communication speed of 38400 baud (half-duplex).

簡介

NCN5150屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由制造生產(chǎn)的NCN5150驅(qū)動(dòng)器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過延長電纜或印制線進(jìn)行通信。確切的功能會(huì)因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對(duì)于通信用途可能并非絕對(duì)必要，但對(duì)于可能的使用環(huán)境卻是明智之選。
