Overview
The MAX5984DETI+T is a single-port Power over Ethernet (PoE) Powered Device (PD) interface controller manufactured by Analog Devices Inc./Maxim Integrated. It supports IEEE 802.3af and 802.3at standards, enabling power delivery up to 40W. The device operates with a supply voltage range of 32V to 60V and features an internal switch. Designed for surface-mount installation, it is housed in a 28-TQFN package measuring 5x5mm. The component functions as a PD interface controller, managing power negotiation and distribution for PoE-enabled applications.
Feature Summary
- Supports IEEE 802.3af and 802.3at PoE standards
- Integrates internal power switch for simplified design
- Operates within a wide supply voltage range of 32V to 60V
- Provides single-channel control for powered devices
Applications
- IEEE 802.3af compliant powered devices
- IEEE 802.3at (PoE+) compliant powered devices
- Network infrastructure equipment requiring integrated PD control
Procurement Notes
Verify the specific suffix 'T' indicates reel packaging when ordering. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated to ensure authenticity. Check current availability status as supply may be limited or subject to factory order constraints. Ensure compatibility with 28-TQFN footprints during PCB layout.
Selection Notes
Select this component for applications requiring certified IEEE 802.3af/at PD integration. The internal switch reduces external component count compared to discrete solutions. Verify that the system input voltage remains within the 32V to 60V operational range. Consider the 28-TQFN package size for space-constrained designs.
Part Context
This part belongs to the MAX5984 series of PoE controllers. It serves as a bridge between the Ethernet physical layer and the local power bus in powered devices. The device simplifies compliance with PoE standards by handling detection, classification, and power management tasks internally.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official distributor databases for cross-reference information if alternative sourcing is required.
