SI3400 Datasheet (Silicon Laboratories) - FULLY-INTEGRATED 802.3-COMPLIANT PD INTERFACE AND SWITCHING REGULATOR

SI3400, FULLY-INTEGRATED 802.3-COMPLIANT PD INTERFACE AND SWITCHING REGULATOR

The Si3400 and Si3401 integrate all power management and control functions required in a Power-over-Ethernet (PoE) powered device (PD) application.

The Si3400 and Si3401 convert the high voltage supplied over the 10/100/1000BASE-T Ethernet connection into a regulated, low-voltage output supply.

The

SI3400 Features

* IEEE 802.3 standard-compliant solution, including pre-standard (legacy) PoE support Highly-integrated IC enables compact solution footprints Minimal external components Integrated diode bridges and transient surge suppressor Integrated switching regulator controller with on-chip power FET Integrated
