제품 개요

The LTC4263IDE#PBF is a 1-channel autonomous PSE Controller with internal switch for use in IEEE 802.3af® compliant power over Ethernet systems. It includes an on board power MOSFET, internal inrush, current limit and short-circuit control, IEEE 802.3af® compliant PD detection and classification circuitry and selectable AC or DC disconnect sensing. Onboard control algorithms provide complete IEEE 802.3af® compliant operation without the need of a microcontroller. The LTC4263 simplifies PSE implementation, needing only a single 48V supply and a small number of passive support components. Programmable on board power management circuitry permits multiple LTC4263s to allocate and share power in multi-port systems, allowing maximum utilization of the 48V power supply, all without the intervention of a host processor. The port current limit can be configured to automatically adjust to the detected PD class. Detection backoff timing is configurable for either Endpoint or Midspan operation.
  • Fully autonomous operation without microcontroller
  • Internal MOSFET with thermal protection
  • Power management works across multiple ports with simple RC network
  • Precision inrush control with internal sense resistor
  • Powered device (PD) detection and classification
  • AC and DC Disconnect sensing
  • Robust short-circuit protection
  • Pin-selectable detection backoff for Midspan PSEs
  • Classification dependent ICUT current threshold
  • LED Driver indicates port on and blinks status codes
