PD69210C-022419

Overview

The PD69210C-022419 is a Power Sourcing Equipment (PSE) controller from Microchip Technology, part of the seventh-generation IEEE 802.3bt-compliant PoE family. It integrates a SAMD21 microcontroller and supports 48 channels with a maximum power of 45W per port. The device operates on a 3.3 V supply voltage within an ambient temperature range of -40°C to +85°C. It is housed in a QFN-32 (5x5 mm) package and complies with IEEE 802.3af/at standards.

Feature Summary

• Integrates a SAMD21 microcontroller for multi-port PoE management
• Complies with IEEE 802.3bt, 802.3at, and 802.3af standards
• Supports up to 48 independent PoE channels
• Designed for high-efficiency power sourcing equipment applications

Applications

• High-density PoE switch designs
• Enterprise network infrastructure
• Power sourcing equipment for LAN environments
• IoT gateway power distribution systems

Procurement Notes

Verify firmware version compatibility during procurement, as the suffix indicates specific firmware release 2.24.19. Confirm package type availability, noting that some distributors list tape-and-reel options while others may reference tray packaging for legacy stock. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the Mouser number 579-PD69210C022419TR or DigiKey listing for accurate current supply status.

Selection Notes

Select this component when designing systems requiring high channel density and strict adherence to IEEE 802.3bt standards. The integrated SAMD21 MCU reduces external component count compared to discrete solutions. Consider the QFN-32 thermal performance for high-power 45W per port implementations. Verify that the host system can support the required 3.3V logic levels and operating temperature range of -40°C to +85°C.

Part Context

This part belongs to Microchip's seventh-generation PoE controller family, specifically based on the PD69210 silicon core. It serves as a firmware-configurable variant, allowing manufacturers to update functionality without changing hardware. The PD692xx series is designed to replace older generations like the PD69200, offering improved efficiency and higher port counts for modern networking equipment.

Replacement Considerations

The PD69220C-022419 is a confirmed substitute within the same family, based on the PD69220 silicon with identical firmware version 2.24.19. Users should verify pin-to-pin compatibility and functional equivalence before substitution. The PD69200C-021119 is an older generation part and is discontinued, making it unsuitable for new designs.
