ON Semiconductor Offers New Power over Ethernet Solutions for IoT Endpoints

According to a recent release, ON Semiconductor is supporting the IEEE 802.3bt standard, with a growing portfolio of compliant products and technologies. Using the new IEEE 802.3bt standard, Power over Ethernet (PoE) can be used to deliver high-speed connectivity up to 90 W of power over Local Area Network (LAN) connections, the company said, and that its solutions support the new standard power limit and extend further to 100 W for systems including telecommunications and digital signage.

The new IEEE 802.3bt standard reportedly enables more sophisticated endpoints operating across larger networks, optimizes energy management, and allows Power Sourcing Equipment to allocate just the right amount of power to each PD, maximizing both the available energy and bandwidth.

With up to 90 W of power available, compared to the 30 W provided by the IEEE 802.at standard (PoE+), IEEE 802.3bt can provide both power and connectivity to new applications that would otherwise require a dedicated and typically off-line power source.

“Power over Ethernet is one of the fastest-growing markets for power semiconductors today, with a compound average unit growth rate of 14% expected from 2017 through 2022,” said Kevin Anderson, senior analyst, power semiconductors, IHS Markit. “The additional power-delivery capability defined in IEEE 802.3bt enables new applications, such as higher-powered connected lighting, networked high-resolution surveillance cameras and high-performance wireless access points.”

“As a company focused on energy efficiency, we are really excited to help PoE achieve its full potential,” said Ryan Cameron, VP, Industrial and Off-Line Power Solutions, ON Semiconductor. “By providing a complete family of IEEE 802.3bt compliant solutions, we have made the technology more accessible for all development engineers which will help enable many more connected devices with guaranteed interoperability.”
