Skyworks Solutions Inc Power-over-Ethernet PD Controller 20-Pin QFN, SI3406-A-GM

The Skyworks Solutions Inc Power over Ethernet PD interface devices fully support the IEEE 802.3at specification for the cases of single or two event classification. Standard external resistors provide the proper IEEE 802.3 signatures for the detection function and programming of the classification mode and internal start up circuits ensure well controlled soft start initial operation of both the hot swap switch and the voltage regulator.
