Overview
The PD39208ILQ-TR-LE is a Power Sourcing Equipment (PSE) manager from Microchip Technology, designed for IEEE 802.3af and 802.3at standards. It integrates eight PoE ports within a single package. The device operates with a supply voltage range of 44 V to 57 V and supports a supply current of 14 mA. It is housed in a 56-pin VFQFN exposed pad package measuring 8x8 mm. The component is rated for industrial operating temperatures ranging from -40°C to 85°C.
Feature Summary
- Fully integrated PSE manager supporting multiple PoE standards
- Eight-channel power sourcing capability
- Industrial temperature rating for harsh environments
Applications
- IEEE 802.3af compliant network infrastructure
- IEEE 802.3at compliant network infrastructure
- Industrial PoE switch designs
Procurement Notes
Verify the specific suffix and tape-and-reel quantity requirements against official Microchip documentation before ordering. Confirm that the 56-VFQFN package dimensions match your PCB layout constraints. Ensure the industrial temperature grade meets your system's operational environment specifications. Cross-reference the RoHS status with current regulatory requirements for your target market.
Selection Notes
Select this component when an integrated solution for eight PoE ports is required without external management complexity. It is suitable for applications adhering to 802.3af and 802.3at standards. Consider the 56-VFQFN package size for space-constrained designs. Verify thermal performance under maximum load conditions within the specified industrial temperature range.
Part Context
This part belongs to Microchip's family of PoE/PSE managers. It shares functional similarities with other models like the PD69208 series but differs in supported standards and port configurations. The PD39208ILQ-TR-LE specifically targets 802.3af/at implementations, distinguishing it from Type 3 or Type 4 variants in the same product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Microchip Technology directly for qualified alternatives or newer revisions of this component.
