Overview
The PD70210ALILQ-TR is an advanced Power over Ethernet (PoE) interface controller designed for powered devices. It complies with IEEE 802.3af and 802.3at standards, supporting single-channel PoE/PoE+ applications. The device integrates a SAMD21 microcontroller to manage multi-port functions and power delivery protocols. Packaged in a 38-QFN (5x7 mm) form factor, it serves as a front-end IC for managing power negotiation and distribution in networked equipment.
Feature Summary
- Integrates a SAMD21 controller for enhanced management capabilities
- Supports IEEE 802.3af and 802.3at PoE standards
- Functions as an advanced front-end interface controller for powered devices
Applications
- Powered Device (PD) implementations in PoE networks
- Multi-port PoE application controllers
- Front-end power management in networked electronic equipment
Procurement Notes
Verify the specific suffix 'LQ-TR' confirms the tape-and-reel packaging format and the QFN-38 package type. Ensure compatibility with IEEE 802.3af/at standards required by your design. Confirm that the integrated SAMD21 controller meets your processing needs without requiring external MCU resources.
Selection Notes
Select this component when designing IEEE 802.3af/at compliant powered devices requiring integrated control logic. The built-in SAMD21 processor reduces external component count compared to discrete solutions. Consider the 38-QFN package constraints for PCB layout and thermal management during the selection phase.
Part Context
This part belongs to Microchip's seventh-generation IEEE 802.3bt-compliant PoE family, although this specific model supports af/at classes. It represents an evolution from earlier PD controllers by incorporating embedded processing capabilities directly into the power interface stage.
Replacement Considerations
Check for direct substitutes within the PD70210 series variants. Verify pinout compatibility if replacing older generation PoE controllers. Ensure any alternative maintains support for the required 802.3af/at classification levels.
