Overview
The MAX5941BCSE+ is a single-channel IEEE 802.3af-compliant Power-Over-Ethernet (PoE) interface and PWM controller designed for Powered Devices (PD). It integrates a complete power IC solution in a 16-SOIC package. The device supports an input voltage range of 18V to 67V with a supply current of 400µA. It delivers a maximum power output of 12.95W. The component operates within a temperature range of 0°C to +70°C and features no internal switch, requiring external power stages.
Feature Summary
- Integrates a fully compliant PD interface with detection and programmable classification signatures
- Includes a compact DC-DC PWM controller suitable for flyback and forward converter designs
- Features integrated MOSFET for isolation and inrush current limiting with programmable control
Applications
- IP Phones
- Wireless Access Nodes
- Internet Appliances
- Computer Telephony Systems

Procurement Notes
Verify the exact suffix designation, as the MAX5941ACSE+ datasheet confirms End-of-Life status for this family. Check if the specific BCSE+ variant is available from authorized distributors or secondary markets, as standard stock may be limited. Confirm RoHS compliance and lead times with suppliers prior to finalizing procurement plans.
Selection Notes
Select this component for applications requiring a compact, single-channel PoE solution compliant with IEEE 802.3af standards. It is suitable for isolated or non-isolated flyback and forward converter topologies. Ensure the design accommodates the 18V to 67V input range and the 16-SOIC thermal constraints for the intended operating environment.
Part Context
This part belongs to the MAX5941A/B series, which combines PoE interface logic with PWM control. It serves as a key component in powering network devices over Ethernet cabling. The BCSE+ designation indicates a specific commercial grade and tape-and-reel packaging option within the broader MAX5941 product line managed by Analog Devices/Maxim Integrated.
Replacement Considerations
Public confirmed substitute part numbers are not explicitly listed in the provided documentation. The MAX5941ACSE+ is noted as End-of-Life; verify availability of the BCSE+ variant or consult manufacturer resources for direct replacements.
