PD64004AH

Overview

The PD64004AH is a fully integrated Power Sourcing Equipment (PSE) manager designed for IEEE 802.3af and 802.3at PoE applications. It features four independent channels with internal switches, supporting a maximum power of 35W per port. The device operates on a supply voltage range of 44V to 57V with a typical supply current of 10mA. It is housed in a 48-QFN (7x7mm) package with an exposed pad and supports industrial operating temperatures from -40°C to +70°C.

Feature Summary

• Fully integrated PSE controller with built-in power switches
• Compliant with IEEE 802.3af and 802.3at standards
• Four-channel architecture for simultaneous PoE delivery

Applications

• PoE+ powered access points
• IP cameras and video surveillance systems
• VoIP phones and conference units
• Wireless LAN controllers

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with Microchip Technology or authorized distributors. Confirm that the 48-VFQFN package matches your PCB footprint requirements. Ensure the supply voltage range aligns with your system's power input specifications before procurement.

Selection Notes

Select this component when designing systems requiring multi-port PoE+ integration with minimal external components. The internal switch capability reduces bill-of-materials complexity compared to discrete solutions. Consider the thermal performance of the exposed pad QFN package for high-power density designs.

Part Context

This part belongs to Microchip's PMIC family focused on Ethernet Power over Ethernet controllers. It serves as a central management unit for powering remote devices over standard Ethernet cabling, replacing older discrete PSE implementations with a single-chip solution.
