Si3472/Si3473 PoE PSE Controllers

Skyworks Solutions Inc. Si3472/Si3473 PoE PSE Controllers are fully programmable, 50V to 57V power sourcing equipment (PSE) controllers. The devices are used for IEEE 802.3bt 2-pair, Type 3 applications. As a 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. Each has IEEE-required detection and classification functionality.
