产品概述

The MAX5971AETI+T is a single port, 40W, IEEE 802.3af/at PSE controller with integrated MOSFET in 28 pin TQFN package. This power sourcing equipment (PSE) power controller is designed for use in IEEE 802.3af/at-compliant PSE. It provides powered device (PD) discovery, classification, current limit and AC/DC load disconnect detections. The device also supports new class 5 and 2 event classification for detection and classification of high power PDs. The MAX5971A provides up to 40W to a single port (class 5 enabled) and still provides high capacitance detection for legacy PDs. It also provides input UVLO, input overvoltage lockout, overtemperature detection, output voltage slew rate limit during start-up and LED status indication. It is typically used in single port PSE end point applications, single port PSE power injectors (midspan applications), switches/routers, wireless LAN access point/WiMAX and base station.
  • Operating voltage range from 32V to 60V
  • Operating temperature range from -40°C to 85°C
  • Integrated 0.5ohm power MOSFET and sense resistor
  • Supply current of 2.5mA and VEE undervoltage lockout of 28.5V
  • Programmable current limit for class 5 PDs
  • High capacitance detection for legacy devices
  • Supports both DC and AC load removal detections
  • Current foldback and duty cycle controlled current limit
  • LED indicator for port status
  • Direct fast shutdown control capability
