MAX5986B - IEEE 802.3af-Compliant High-Efficiency PDs

Download the MAX5986B datasheet PDF. This datasheet also covers the MAX5986A variant, as both devices belong to the same ieee 802.3af-compliant high-efficiency pds family and are provided as variant models within a single manufacturer datasheet.

Description

The MAX5986A

MAX5986C/MAX5987A provide a complete power-supply solution as IEEE® 802.3afcompliant Class 1/Class 2 Powered Devices (PDs) in a Power-over-Ethernet (PoE) system.

Features

  • High Integration Saves Space and BOM Cost.
  • Efficient, Integrated DC-DC Converter (with Integrated Switches).
  • Built-In Output-Voltage Monitoring.
  • Protects Against Overload, Output Short Circuit, Output Overvoltage, and Overtemperature.
  • Integrated TVS Diode Withstands Cable Discharge Event (CDE).
  • Internal LDO Regulator with Up to 100mA Load (MAX5987A).
  • IEEE 802.3af-Compliant Features Reduce Design Time.
  • PoE Class 1/Cl.

MAX5986A–MAX5986C/ MAX5987A EVALUATION KIT AVAILABLE IEEE 802.3af-Compliant, High-Efficiency, Class 1/Class 2, PDs with Integrated DC-DC Converter General Description The MAX5986A–MAX5986C/MAX5987A provide a complete power-supply solution as IEEE® 802.3afcompliant Class 1/Class 2 Powered Devices (PDs) in a Power-over-Ethernet (PoE) system. The devices integrate the PD interface with an efficient DC-DC converter, offering a low external part count PD solution. The MAX5987A includes a low-dropout regulator and the MAX5986A– MAX5986C include sleep and ultra-low power modes. The PD interface provides a detection signature and a Class 1/Class 2 classification signature with a single external resistor.
