powered device (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. The Si3471 works autonomously and does not require a host or MCU to program it. The Si3471 is programmed for maximum available power by pulling its configration pins high or low.
