Power microchip PSE

New PoE PSE Chipsets for the IEEE® 802.3 at Market Segment Microchip’s new PSE chipsets are specifically designed for the many applications of the sub 30W PoE market segment. Keep reading to learn why. Power over Ethernet (PoE) technology eliminates the need for AC power for Ethernet connected devices. The IEEE® 802.3bt standard allows for connected devices to consume up to 90W of power. This “BT” version of the IEEE specification widens the application space to virtually any device with an Ethernet connection to be powered over the Ethernet cable. Flat-panel monitors, point-of-sale terminals and information kiosks are just a few of the latest applications to adopt PoE. However, developing products using chip sets to support the BT standard and the higher power does come at a higher cost. The BT standard was ratified in 2018, yet the majority of the PoE devices on the market today such as Wi-Fi™ access points, security cameras and IP telephones still consume less than 30W of power. Yes, BT equipment will still power these devices, but lower cost power sourcing equipment (PSE) that supports the IEEE 802.3at standard with 30W maximum can still be deployed to power these “AT” devices — allowing IT departments to save money on PoE enabled equipment. Microchip recently announced its new PoE PSE chip sets, specifically designed for the AT market segment. The PD69201 is a single channel PSE device while the PD39210 and PD39208 are a PoE PSE controller, plus a manager chip set that scales to support 8 to 48 channels.
