include 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 2-pair 802.3bt standards. Intelligent power protection circuitry includes input undervoltage detection, output power limit, and short-circuit protection. The Si3473/72 operates autonomously or by host processor control through a two wire, I2C-compatible serial interface. An interrupt pin is used to alert a host processor of various status and fault event.
