PD77020-020300-TR

Overview

The PD77020-020300-TR is a firmware update package for the Microchip PD77020 IEEE 802.3bt PoE PSE Power Management Controller. It contains firmware version 2.03.00 designed for the PD770xx family. The component utilizes a 32-pin VQFN (5x5 mm) package and operates within a temperature range of -40°C to +125°C. It is supplied in tape and reel packaging, facilitating automated surface-mount assembly processes for network infrastructure equipment requiring compliant power sourcing.

Feature Summary

Provides updated firmware logic for IEEE 802.3bt PoE++ power sourcing equipment controllers
Ensures compatibility with the PD770xx microcontroller family architecture
Supports enhanced power management protocols for high-power Ethernet applications

Applications

IEEE 802.3bt Power Sourcing Equipment (PSE) implementations
High-power PoE network switches and injectors
Industrial networking infrastructure requiring certified power delivery

Procurement Notes

Verify that the target hardware utilizes the PD77020 controller before procurement. Confirm that the firmware version 2.03.00 is compatible with the specific application requirements and existing system configurations. Ensure proper handling procedures are followed for the VQFN package during installation.

Selection Notes

Select this part when upgrading or initializing PD77020-based designs with the specified firmware revision. Consider the 32-QFN footprint constraints and thermal management needs associated with high-power PoE applications. Validate that the operating temperature range meets the environmental conditions of the intended deployment site.

Part Context
