MAX5995C Datasheet Powered Device Interface Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: EVALUATION KIT AVAILABLE Click here for production status of specific part numbers. MAX5995A/B/C IEEE 802.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX5995A/MAX5995B/MAX5995C provide a plete interface for a powered device (PD) to ply with the IEEE® 802.3af/at/bt standard in a Power-Over-Ethernet (PoE) system.

The devices provide the PD with a detection signature, classification signature, and an integrated isolation power switch with startup inrush current control.

During the startup period, the devices limit the current to 135mA (typ) before switching to the higher current limit (1800mA to 2400mA, typ) when the isolation power MOSFET is fully enhanced.

Key Features

  • IEEE 802.3af/at/bt Compliant.
  • Type 1~4 PSE Classification Indicator or an External Wall Adapter Indicator Output.
  • Simplified Wall Adapter Interface.
  • Multi-Event Classification 0.
  • 8.
  • Intelligent MPS (MAX5995B/MAX5995C, Patent US9152161).
  • Sleep Mode and Ultra-Low-Power Sleep Mode (MAX5995A/MAX5995B).
  • 100V Input Absolute Maximum Rating.
  • Inrush Current Limit During Startup.
  • Current Limit During Normal Operation.
  • Current Foldback Protection.
