a fully-programmable architecture that enables powered device (PD) disconnect using dc-sense algorithms, a robust multipoint detection algorithm, software configurable per-port current and voltage monitoring, and programmable current limits to support the IEEE 802.3af, 802.3at, and 802.3bt standards. Intelligent protection circuitry includes input undervoltage detection, output current limit, and short-circuit protection. The Si3474 operates autonomously or by host processor control through a tw.
