Si3473 Octal or Quad 2-pair 802.3bt Ethernet Port PoE PSE Controller

Si3473/72 Data Sheet Octal or Quad 2-pair 802.3bt Ethernet Port PoE PSE Controller The Si3473 and Si3472 are fully programmable, 50 V to 57 V power sourcing equipment (PSE) controllers for IEEE 802.3bt 2-pair, Type 3 applications. As 2-pair, Type 3 PSE controllers, Si3473/72 are compatible with IEEE 802.3af and IEEE 802.3at powered device (PD) loads. Designed for use in PSE endspans (switches) and midspans (injectors), the Si3473/72 integrates eight (Si3473) or four (Si3472) independent ports, .

Si3473 Features

* 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.
