Accelerating building automation with KNX and PoE

10-06-2022 | ON Semiconductor | Semiconductors

Onsemi has introduced two complete system solutions supporting the most broadly employed building automation network protocols - PoE and KNX.

The NCN5140S is the first SiP certified with the KNX Association to simplify the development of access and control panels. The device combines all critical and certifiable elements of a KNX device, incorporating a digital KNX transceiver, a 32-bit Arm Cortex-M0+ microcontroller with a pre-certified software stack, and system power DC-DC converters, into a single package. With its high degree of integration, it considerably lowers material costs. It allows manufacturers to develop slim and modern designs (<5mm total depth).

The company has also released a complete solution for ethernet-powered connected lighting. Unique to any other device on the market, the NCL31010 incorporates an intelligent LED driver and PoE interface into a single package. This supports the lighting and power delivery demands of fully connected and managed lighting systems.

“As building automation installations continue to gain greater momentum, the industry needs solutions that incorporate necessary functionality in a simple, compact package,” said Michel De Mey, vice president of the Industrial Solutions Division, onsemi. “With our pre-certified KNX SiP and new intelligent LED driver, onsemi provides manufacturers with the latest technology, and the head start they need to develop complex, full-scale automation systems in a shorter time.”

The IEEE 802.3bt compliant NCL31010 can provide over 90W via PoE. An innovative application for this device, made possible by the highly efficient buck LED driver, is called Visible Light Communication (VLC). This involves modulating data directly onto the LED light, which remains imperceptible to the human eye, enabling it to broadcast data and function as a location beacon for indoor positioning systems.
