Product Overview

The LM5072MH-80 is an integrated 100V Power over Ethernet Powered Device Interface and PWM Controller with aux support provides a complete power solution, fully compliant to IEEE 802.3af, for the PD connecting into Power over Ethernet (PoE) networks. This controller integrates all functions necessary to implement both a PD powered interface and DC-DC converter with a minimum number of external components. It provides the flexibility for the PD to also accept power from auxiliary sources such as AC adapters in a variety of configurations. The low RDS(ON) PD interface hot swap MOSFET and programmable DC current limit extend the range of controller applications up to twice the power level of 802.3af compliant PD devices. The 100V maximum voltage rating simplifies selection of the transient voltage suppressor that protects the PD from network transients. It includes an easy-to-use PWM controller that facilitates the various single-ended power supply topologies.
  • Integrated PD Signature resistor
  • Integrated PoE input UVLO
  • Programmable inrush current limit
  • PD Classification capability
  • Power good indicator
  • Thermal shutdown protection
  • Current mode PWM controller
  • Error amplifier with 2% Voltage reference
  • Supports isolated and non-isolated applications
  • Programmable oscillator frequency
  • Programmable soft-start
  • 800mA Peak gate driver
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.
