New KNX Twisted Pair Controller Integrated Circuits from ON Semiconductor
ON Semiconductor introduced three new KNX controllers: NCN5121 and NCN5130 contain the complete KNX PHY and MAC layers, NCN5110 is an analog-only bit transceiver.
New features include a fixed 3.3V and a programmable 1.2-21V DC-DC controller, an analog signal monitoring output, option to work with one crystal in the application, excellent efficiency by a proprietary energy recuperation method. The minimum bus coupler capacitor is reduced to 27µF.
NCN5130 DC-DC controllers can draw 100mA; total allowable bus current is increased to 40mA.
All parts come in 6x6 QFN-40 pin packages and have a junction temperature range of -40 to 125°. Evaluation boards with user manuals and documentation are available.
