Overview
The MAX5942ACSE+ is a Power-Over-Ethernet (PoE) controller designed for Powered Devices (PDs) compliant with the IEEE 802.3af standard. It integrates a PD interface and a DC-DC PWM controller suitable for flyback and forward converters in isolated or non-isolated designs. The device operates within a supply voltage range of 18V to 67V, drawing a supply current of 400µA. It supports a maximum power output of 12.95W and functions within an operating temperature range of 0°C to 70°C. The component is housed in a 16-SOIC package.
Feature Summary
- Integrates IEEE 802.3af-compliant PD interface with detection and classification signatures
- Includes compact DC-DC PWM controller for isolated and non-isolated converter topologies
- Features integrated isolation switch with programmable inrush current control
Applications
- Powered Device (PD) interface implementation in PoE systems
- Flyback converter design for PoE applications
- Forward converter design for PoE applications
Procurement Notes
Verify component authenticity through authorized distributors due to End-of-Life status. Confirm RoHS compliance and specific suffix variations against official datasheets. Check for obsolescence notices from Analog Devices. Ensure supply chain stability as availability may be restricted.
Selection Notes
Select this component for designs requiring integrated PoE detection and power conversion control. Suitable for applications needing IEEE 802.3af compliance without external interface logic. Consider thermal management for 12.95W power handling. Verify input voltage compatibility with the 18V-67V range.
Part Context
Part of the Maxim Integrated MAX5942 family of PoE controllers. Designed to simplify Powered Device development by combining interface and power management functions. Replaced by newer generations in some portfolios but remains documented for legacy system maintenance.
Replacement Considerations
Consult official documentation for direct substitutes. The MAX5941ACSE+ offers similar PoE functionality. Verify pinout and feature compatibility before substitution.
