Overview
The MAX5969EETE+ is a single-channel Power over Ethernet (PoE) controller compliant with IEEE 802.3at and 802.3af standards. It operates within a source voltage range of 40V to 60V and draws a supply current of 270µA. The device supports up to 25.5W of power delivery and features an internal switch. It is housed in a 16-TQFN package with exposed pad, suitable for surface-mount assembly across an operating temperature range of -40°C to +85°C.
Feature Summary
- Supports IEEE 802.3at (PoE+) and 802.3af (PoE) protocols
- Integrates an internal power switch
- Includes auxiliary detection capability
Applications
- Power sourcing equipment (PSE)
- Ethernet-powered devices requiring PoE/PoE+ compliance
Procurement Notes
Verify the specific suffix 'EETE' against official Analog Devices documentation to confirm tape-and-reel packaging and temperature grade. Confirm RoHS status and lead-free composition via the manufacturer's certificate. Ensure the component matches the 16-TQFN footprint and pinout requirements for your PCB design before finalizing procurement.
Selection Notes
Select this component for applications requiring a single-channel PoE solution with integrated switching. It is suitable for designs needing support for both 802.3af and 802.3at standards within a compact 16-TQFN package. Consider the 40V-60V input range and 270µA supply current when designing the power management circuitry.
Part Context
The MAX5969 series belongs to Analog Devices' portfolio of Power over Ethernet controllers. This specific part integrates control logic and a power switch into a single channel, simplifying the design of PSE systems. It is part of the broader Maxim Integrated line of mixed-signal solutions for networking infrastructure.
Replacement Considerations
Check for direct cross-reference part numbers from Analog Devices or other manufacturers offering IEEE 802.3af/at compatible single-channel PoE controllers in a 16-TQFN package. Verify pin compatibility and electrical specifications before substitution.
