SI3402-B Datasheet Fully-integrated 802.3-compliant Poe Pd Interface And Low-emi Switching Regulator

Manufacturer: Silicon Laboratories

Overview: Si3402-B FULLY-INTEGRATED 802.3-COMPLIANT POE PD INTERFACE AND LOW-EMI SWITCHING.

General Description

 Point-of-sale terminals  Internet appliances  Network devices  High power applications The Si3402 integrates all power management and control functions required in a Power-over-Ethernet (PoE) powered device (PD) application.

The Si3402 converts the high voltage supplied over the 10/100/1000BASE-T Ethernet connection into a regulated, low-voltage output supply.

The optimized architecture of the Si3402 minimizes the solution footprint, reduces external BOM cost, and enables the use of low-cost external components while maintaining high performance.

Key Features

  • Pin-compatible replacement for the obsolete Si3402-A.
  • 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.
  • Programmable classification circuit.
  • Incorporates switc.
