POE+ powered device family for high-wattage IoT applications

Mouser now offers the Si3406x POE+ PD family from Silicon Labs. Combining all necessary high-voltage discrete components on a single PD chip, the family devices lessen the time to market and system cost for a variety of high-efficiency, high-power POE+ PD applications. The ICs deliver 30W of power to support feature-rich IoT products like VoIP devices, motor-positioned IP and security cameras, and other industrial devices. As the demand for high-wattage IoT applications increases, developers must rely on powered devices that support the POE+ standard. The POE+ PD family ICs convert the high voltage supplied over Ethernet copper cabling into a regulated, low-voltage DC supply. The ICs offer a broad array of feature options, including reduced EMI, flexible power conversion options, a robust sleep mode augmented with mode control, wake pin, and LED driver, and full IEEE 802.3at compliance. The POE+ PD family includes the flagship Si3406 IC as well as the Si34061 variant, which adds support for external FETs and to improve power conversion efficiency, and the Si34062 variant, which includes support for sleep modes with wake function, as well as LED drive capability. The 20-pin Si3406 IC and 24-pin Si34061 and Si34062 are housed in a compact, 5mm x 5mm QFN package, and support an operating temperature range of -40C to 85C.
