Product Overview

The LM5071MT-80/NOPB is a power over Ethernet PD Controller with auxiliary power interface. This controller provides a complete integrated solution for Powered Devices (PD) that connects into Power over Ethernet (PoE) systems. The LM5071 is specifically designed for the PD that must accept power from auxiliary sources such as AC adapters. The auxiliary power interface of the controller activates the PWM controller when the AC adapter is connected to power the PD when PoE network power is unavailable and integrates an 80V, 400mA line connection switch, associated control for a fully IEEE 802.3af compliant interface with a full featured current mode pulse width modulator DC-DC converter. All power sequencing requirements between the controller interface and switch mode power supply (SMPS) are integrated into the IC.
  • Compatible with 12VAC adapters
  • Fully compliant 802.3af power interface port
  • Detection resistor disconnect function
  • Programmable classification current
  • Programmable under-voltage lockout with programmable hysteresis
  • Thermal shutdown protection
  • Auxiliary power enable pin
  • Current mode pulse width modulator
  • Supports both isolated and non-isolated applications
  • Error amplifier and reference for non-isolated applications
  • Programmable oscillator frequency
  • Programmable soft-start
  • Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
