PD64012GH

Overview

The PD64012GH is a twelve-port, mixed-signal, high-voltage Power over Ethernet PSE Manager manufactured by Microsemi Corporation. It supports IEEE 802.3af-2003 and 802.3at (PoE+) standards for powered device detection and power delivery. The integrated circuit manages power distribution across twelve channels within a single package. It features high-voltage operation capabilities suitable for enterprise networking infrastructure. The component is housed in a 64-lead LQFP package.

Feature Summary

• Manages twelve independent PoE ports with mixed-signal control
• Supports IEEE 802.3af and 802.3at powered device classification
• Integrates high-voltage power management logic
• Provides centralized PSE controller functionality

Applications

• Enterprise network switches
• High-density PoE midspan injectors
• Access point aggregation systems
• IP camera surveillance hubs

Procurement Notes

Verify the specific suffix 'GH' against official Microsemi documentation to confirm pinout and thermal specifications. Confirm RoHS compliance status through current datasheets as product lifecycles may change regulatory classifications. Ensure compatibility with existing PCB footprints for the 64LQFP package before integration into new designs.

Selection Notes

Select this component when a single-chip solution for twelve PoE ports is required. It is suitable for designs needing integrated classification and power sequencing without external discrete controllers. Consider thermal dissipation requirements due to the high-voltage mixed-signal nature of the device within the dense LQFP package.

Part Context

This part belongs to the Microsemi PD64xx series of PoE managers. It serves as a central controller for multi-port Ethernet power distribution. The series is designed to simplify the implementation of compliant Power over Ethernet endpoints in structured cabling environments.

Replacement Considerations

Check for direct cross-reference part numbers from Microsemi or acquired entities like Microchip Technology. Verify if alternative packages offer identical electrical characteristics for board-level upgrades.
