ON Semiconductor announced six electronics products that take advantage of the new Power over Ethernet (PoE) standard for use with smart sensors, building automation and connected lighting.
The new IEEE standard, known as 802.3bt, allows delivery of up to 90 watts of power over Local Area Network (LAN) connections.
ON Semiconductor announced it has extended the standard further to 100 watts for telecommunications and digital signage systems. The prior IEEE 802.at standard provided just 30 watts of power.
The new standard relies on an autoclass feature to enable powered devices (PDs) to communicate specific power needs to Power Source Equipment (PSE). In turn, the PSE allocates the right amount of power to each PD for energy and bandwidth efficiency.
They provide detection, auto-classification and current limiting features. These two controllers are complemented by the NCP1566 DC-DC Controller and a FDMC8622 Single MOSFET and two Greenbridge Quad MOSFETs, the FDMQ8203 and FDMQ8205A. Pricing wasn’t disclosed.
PoE is a fast-growing market for power semiconductors, with 14% annual growth through 2022, said Kevin Anderson, an analyst at IHS Markit. The added power delivery in 802.3bt enables such applications as higher-power connected lighting, networked high-resolution surveillance cameras and high-performance wireless access points.
