Product details
Overview
PD69220R-022620 from Microchip Technology is a Generation 6 IEEE 802.3af/at/bt and HDBaseT-compliant PoE Power Sourcing Equipment (PSE) controller supporting up to 48 logical ports, 45W per port, and dual 2-pair/4-pair power delivery in Ethernet switches. It integrates with PD69208T4/PD69204T4/PD69208M managers via SPI and supports I2C or UART host communication at 19.2 kbps.
For engineers reviewing the PD69220R-022620 datasheet, PD69220R-022620 pinout, PD69220R-022620 application, or PD69220R-022620 equivalent, key selection criteria include its LGA 5 mm × 5 mm package, per-port power management modes (Class/Static/Dynamic), legacy PD detection capability, Fast PoE boot, and Perpetual PoE during host firmware upgrades.
Technical Context
The PD69220R-022620 implements a dual-interface (I2C or UART) host control architecture with configurable address selection via analog input pin I2C_ADDR_MEAS (Pin 22), and uses SPI (1 MHz) to coordinate with up to 12 PoE managers. Its firmware is pre-programmed, field-upgradeable, and vendor-agnostic.
It features hardware-level system monitoring including xSys_OK (active-low system validity), xDISABLE_PORTS (active-low global port shutdown), xINT_OUT (active-low event interrupt), and dedicated LED stream control (xLED_OE, xLED_CS, xLED_LATCH2) for status indication across large-scale PoE deployments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PoE PSE controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PD69210D1VVVV2SS3 | Identical feature set but 32-pin QFN (not LGA); different pinout layout; θJA = 40.9°C/W vs 65.0°C/W. | Preferred for new designs where thermal performance is critical and PCB layout flexibility allows QFN footprint. | Select PD69210 when board space permits larger thermal pad copper area and lower junction-to-ambient resistance is required. |
| PD69200 | Previous-generation controller; lacks IEEE 802.3bt and HDBaseT support; no Fast/Perpetual PoE; MSL level 1 vs level 3. | Suitable only for legacy 802.3af/at systems with no upgrade path to bt-class power or enhanced reliability features. | Choose PD69200 only for cost-sensitive brownfield replacements where 802.3bt is not needed and MSL3 handling is unavailable. |
Compared with PD69210 and PD69200, PD69220R-022620 delivers identical PoE functionality in an LGA package optimized for PD69200 footprint compatibility, higher MSL tolerance, and simplified thermal design - making it ideal for industrial upgrades requiring minimal PCB rework and extended lifecycle support.

FAQ
What IEEE PoE standards does the PD69220R-022620 support?
The PD69220R-022620 supports IEEE 802.3af, 802.3at, 802.3bt, and HDBaseT (PoH) standards. It enables full interoperability with Class 0–8 PDs and delivers up to 45W per port in 2-pair or 4-pair configurations. This compliance is verified in the official DS00003424D datasheet and confirmed through Microchip's AN3361 application note for 48-port PoE system design.
How does the PD69220R-022620 differ from the PD69210 in terms of package and thermal performance?
The PD69220R-022620 uses a 32-pin laminated QFN (LGA) 5 mm × 5 mm package with θJA = 65.0°C/W, while the PD69210 uses a standard QFN with θJA = 40.9°C/W. The PD69220R-022620 is pin-compatible with PD69200 and offers MSL level 3 versus PD69210's MSL level 1, enabling more flexible handling and storage in production environments.
Can the PD69220R-022620 operate without a host processor?
Yes, the PD69220R-022620 can operate standalone using pre-programmed firmware with default profiles. It supports autonomous port power-up (Fast PoE), maintains power during host reset (Perpetual PoE), and executes per-port power management without host intervention - though I2C or UART is required for configuration, monitoring, and firmware updates.
What is the function of Pin 22 (I2C_ADDR_MEAS) on the PD69220R-022620?
Pin 22 (I2C_ADDR_MEAS) is an analog input that selects between I2C and UART host interfaces and sets the 7-bit I2C address via an external resistor divider. This eliminates the need for configuration pins or EEPROM, allowing flexible interface selection and addressing without modifying firmware or PCB layout - a key differentiator from earlier generation controllers.
Does the PD69220R-022620 support legacy (pre-standard) PD detection?
Yes, the PD69220R-022620 supports per-port legacy PD detection, enabling reliable identification and powering of pre-IEEE 802.3af devices. This capability is explicitly documented in Table 1 (Features Matrix) of the DS00003424D datasheet and is essential for brownfield deployments integrating older VoIP phones or security sensors into modern PoE infrastructure.
