Si34071 Data Sheet
The Si34071 integrates the signaling, control, and power conversion functions required in a Power over Ethernet 802.3btpowered device (PD) application.
The optimized architecture minimizes the solution footprint and external BOM while using standard, low cost components. The integrated PoE PD interface fully complies with the IEEE 802.3bt standard and uses external resistors to program the requested classification and detection signatures. Connection to the PSE switch is maintained during no-load condition by an optional maintain-power-signature (MPS) signal. An internal, current-mode controlled switching regulator converts the high voltage supplied over the 10/100/1000BASE-T Ethernet connection to a regulated, low-voltage output supply.
