Si3474 - Up to four 802.3bt or eight 802.3at Ethernet Port PoE PSE Controller

Si3474 Data Sheet Up to four 802.3bt or eight 802.3at Ethernet Port PoE PSE Controllers The Si3474 is a fully programmable, 50 to 57 V power management controller for IEEE 802.3af, 802.3at, and 802.3bt compliant Power Sourcing Equipment (PSE). Designed for use in PSE endpoints (switches), the Si3474 integrates eight independent ports, each with the IEEE-required powered device (PD) detection and classification functionality. When used in 802.3af/802.3at (two-pair power) mode each PSE port suppo.

Si3474 Features

* 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
