SI3401 - FULLY-INTEGRATED 802.3-COMPLIANT PD INTERFACE AND SWITCHING REGULATOR

Download the SI3401 datasheet PDF. This datasheet also covers the SI3400 variant, as both devices belong to the same fully-integrated 802.3-compliant pd interface and switching regulator family and are provided as variant models within a single manufacturer datasheet.

Description

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.

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 dual current-limited hotswap switch Support non-isolated and isolated switching topologies Comprehensive protection circuitry Transient overvoltage protection Undervoltage lockout Early power-loss in.
