Introducing the Silvertel Ag59FE: A New Flexible, High‑Power PoE PD Controller Module

Power-over-Ethernet has evolved rapidly, and modern applications—from smart lighting to industrial networking—demand more power, more intelligence, and more configuration flexibility than ever before. The new Silvertel Ag59FE meets that challenge head‑on.

Designed and manufactured in the UK, the Ag59FE is a compact, highly configurable IEEE802.3af/at/bt Powered Device (PD) controller module capable of requesting up to 90W from compliant Power Sourcing Equipment (PSE). This makes it one of the most versatile PD front ends available for designers building next‑generation PoE-powered systems.

Key Features That Set the Ag59FE Apart

The module brings together a rich set of capabilities in a small 35mm × 14mm footprint:

  • Full IEEE802.3af/at/bt compliance for universal interoperability
  • Configurable power classification (Class 0–8) via simple resistor programming
  • Power Good output for safe, sequenced system startup
  • Maintain Power Signature (MPS) support for low‑power standby modes
  • PoE disable control for hybrid‑power or auxiliary‑powered systems
  • Minimal external components—just bridge rectifiers and optional protection
  • Industrial temperature range (–40°C to +85°C)
  • SIL or SMT mounting options for flexible manufacturing

Smarter Power Negotiation and Type Detection

Modern PoE systems must adapt to the capabilities of the connected PSE. The Ag59FE includes dual type‑detect outputs (TYP2‑DET and TYP3‑DET) that allow the host system to understand exactly what power level is available.

This enables applications to gracefully scale performance, warn users of insufficient power, or avoid brown‑out conditions.

Maintain Power Signature for Ultra‑Low Power Designs

For devices that spend long periods in standby—such as sensors, lighting nodes, or remote monitors—the Ag59FE includes an intelligent MPS system. It automatically generates the required pulsed load to keep the PSE connection alive while minimising energy use. Designers can even disable MPS dynamically via the MPS_DIS pin for deeper sleep modes.

Ideal Applications

The Ag59FE is a natural fit for:

  • PoE lighting and building automation
  • Ethernet media converters
  • Industrial sensors and control nodes
  • Remote cameras and security devices
  • Smart signage and kiosks
  • Any system needing up to 90W PoE input with minimal design overhead

Its small footprint and SIL/SMT flexibility make it easy to integrate into both new designs and existing product families.

A Powerful, Configurable Foundation for PoE Designs

The Ag59FE brings together the essential elements of a modern PoE PD controller—high power capability, flexible classification, intelligent MPS handling, and simple integration. For engineers looking to accelerate development while maintaining full IEEE compliance, it offers a clean, robust, and compact solution.
