Overview

Si3453 QUAD HIGH-VOLTAGE PORT CONTROLLER FOR POE AND POE+ PSES.

Key Features

  • Each Si3453 high-voltage port.
  • Programmable architecture supports controller supports four PSE power IEEE 802.3af (PoE) and IEEE interfaces 802.3at (PoE+) PSEs.
  • Programmable current limits for PoE.
  • Programmable current limits for (15.4 W), PoE+ (30 W), and PoE (350 mA) and PoE+ proprietary systems (up to 40 W) per (600 mA), and custom limits to port 850 mA.
  • I2C interface requires no external.
  • Per-port current and voltage MCU for easy, low-cost managem.
