Datasheet Summary
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 patible 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, each with the IEEE-required detection and classification functionality.
In addition, the Si3473/72 Features include powered device (PD) disconnect using dc-sense algorithms, a robust multipoint...
