Product Overview

The LTC4263CDE-1#PBF is a high power single PSE Controller for use in power over Ethernet systems. The internal current limit and short-circuit protection are designed to provide up to 30W of PSE output power for power hungry PoE applications such as WAPs, security cameras and RFID readers. The LTC4263-1 includes IEEE 802.3af® compliant PD detection circuitry along with selectable AC and DC disconnect sensing, allowing seamless operation in conventional IEEE 802.3af® systems as well as propriety, high power applications. The LTC4263-1 simplifies PSE implementation, needing only a single supply and a small number of passive support components. Onboard control algorithms provide complete PSE functionality without the need of a microcontroller and built-in foldback and thermal shutdown provide comprehensive fault protection. An LED pin indicates the state of the port and detection backoff timing is configurable for either endpoint or midspan operation.
  • Fully autonomous operation without a microcontroller
  • Internal MOSFET with thermal protection
  • Precision inrush control with internal sense resistor
  • Forced current PD detection for noise immunity
  • AC and DC Disconnect sensing
  • Legacy PD detection
  • Robust short-circuit protection
  • Pin-selectable detection backoff for Midspan PSEs
  • LED Driver indicates port on and blinks status codes
