The Si3471A-A01-IM from Skyworks Solutions is a fully autonomous Power over Ethernet (PoE) Power Sourcing Equipment (PSE) device. It is compliant with IEEE 802.3bt standards and compatible with IEEE 802.3af and 802.3at.
This device is optimized for use in PSE mid-spans and injectors that do not require a host or MCU. It integrates one Ethernet port with the IEEE-required powered device (PD) detection and classification functionality. The Si3471A-A01-IM features PD disconnect using DC sense algorithms and a robust multipoint detection algorithm. Intelligent protection circuitry includes input undervoltage detection, output current limit, and short-circuit protection.
Key features include comprehensive fault protection, including power undervoltage lockout, output current limit, short-circuit protection, and thermal overload detection. The device operates autonomously and is programmed for maximum available power by pulling its configuration pins high or low. It is supplied in a 38-pin, 5 x 7 mm QFN package suitable for surface mounting.
Applications for the Si3471A-A01-IM include IEEE 802.3af, 802.3at, and 802.3bt Power Sourcing Equipment (PSE), Power over Ethernet Injectors, Single Port Mid-Spans, Power over Ethernet Switches, IP Phone Systems, Smartgrid Switches, and Ruggedized and Industrial Switches.
