Product details
Overview
PD69220C-022619 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.
For engineers reviewing the PD69220C-022619 datasheet, PD69220C-022619 pinout, PD69220C-022619 application, or PD69220C-022619 equivalent, key selection criteria include its LGA 5 mm × 5 mm package, per-port power limiting, legacy PD detection, perpetual PoE capability, and pin-compatible upgrade path from PD69200.
Technical Context
The PD69220C-022619 implements a firmware-controlled PSE architecture based on the SAM D21 core, enabling autonomous port management without continuous host intervention. It executes IEEE 802.3bt Class 8 power classification, supports dynamic/static/class-based power allocation modes, and delivers fast PoE boot sequencing independent of host initialization.
Its dual-interface design allows flexible host integration: I2C (7-bit address, clock stretch required, 400 kHz max) or UART (19.2 kbps, 8N1), selected via analog voltage on I2C_ADDR_MEAS (Pin 22). Communication uses a deterministic 15-byte protocol for telemetry, command, and fault reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Standards | Complies with 802.3af, 802.3at, 802.3bt, and HDBaseT (PoH) - enables full backward compatibility and high-power 4-pair delivery up to 90W system-wide. |
| Logical Ports | Supports up to 48 logical ports - allows scalable switch designs from 8- to 48-port systems using 2× physical ports per logical port. |
| Max Per-Port Power | 45W - meets IEEE 802.3bt Type 3 (Class 6) and Type 4 (Class 8) requirements when paired with compatible managers. |
| Supply Voltage | VDD = 3.0–3.63 V - operates from standard 3.3V rail; VDDA and VDD_CORE (1.2V) require separate decoupling per datasheet layout guidelines. |
| Operating Temp | –40°C to +85°C - qualified for industrial Ethernet switch environments including uncontrolled chassis thermal zones. |
| Package | 32-pin LGA, 5 mm × 5 mm - surface-mount land grid array with ePAD thermal pad; requires exact paste mask per Figure 4-8 for reliable reflow. |
| Communication | I2C or UART - selectable via Pin 22; I2C supports multi-controller addressing (0x04–0x3C); UART uses fixed 19.2 kbps, 8N1 framing. |
Pinout & Package
PD69220C-022619 is housed in a 32-pin plastic laminated QFN (LGA), 5 mm × 5 mm, with exposed thermal pad (ePAD) requiring connection to VSSA and adequate copper mass for θJA = 65.0°C/W thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 22 (I2C_ADDR_MEAS) | Analog input | Selects UART vs. I2C interface and sets 7-bit I2C address (0x04–0x3C) via external resistor divider; critical for multi-controller bus configuration. |
| Pin 4 (xDISABLE_PORTS) | Digital input | Active-low global shutdown - asserts low to disable all PoE ports simultaneously; used for emergency power cutoff or system-level safety interlock. |
| Pin 25 (xINT_OUT) | Open-drain output | Active-low interrupt signal - indicates port on/off, fault, voltage out-of-range, or PD detection completion; enables event-driven host polling. |
| Pin 24 (xI2C_MESSAGE_READY) | Open-drain output | Active-low handshake - signals host that I2C response data is ready for read; eliminates need for fixed delay or timeout in host firmware. |
| Pin 23 (xLED_CS) | Digital output | Active-low chip select for external LED stream - synchronizes status lighting across multiple PoE ports via dedicated SPI peripheral. |
| ePAD | Thermal & ground | Must be connected to VSSA with ≥4 thermal vias; primary heat dissipation path - insufficient copper mass degrades θJA and risks thermal shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Perpetual PoE | Maintains powered state to connected PDs during host firmware update or reset - ensures zero downtime for VoIP phones, cameras, or wireless APs. |
| Legacy PD Detection | Identifies and powers pre-standard IEEE devices using reduced capacitance detection - preserves interoperability with older VoIP endpoints and IP intercoms. |
| Fast PoE Boot | Initiates port power-up within milliseconds of power-on, independent of host CPU boot sequence - reduces time-to-service for managed switches. |
| Port Power Limiting | Configurable per-port wattage cap (e.g., 15.4W, 30W, 60W); automatic disconnect on violation - prevents overloading of upstream power supplies and protects cabling infrastructure. |
| System OK Indication | xSys_OK/LED (Pin 31) provides active-low digital status - drives host MCU GPIO or external LED to signal valid PoE subsystem operation after self-test and manager handshake. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PoE PSE controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PD69210C-022619 | Identical feature set but 32-pin QFN (not LGA); θJA = 40.9°C/W vs. 65.0°C/W; pinout differs - not PCB-compatible. | Preferred where thermal budget permits and existing QFN layout exists; lacks PD69200 footprint compatibility. | Select PD69210C-022619 only if board space allows QFN thermal pad routing and no migration from PD69200 is required. |
| PD69200C-022619 | Generation 5 controller; supports only 802.3af/at (no 802.3bt or HDBaseT); 24-port max; no perpetual PoE or fast boot. | Suitable for cost-sensitive 24-port switches requiring basic PoE+; cannot scale to 48 ports or deliver >30W/port. | Choose PD69200C-022619 only for legacy redesigns with unchanged port count and power class; not viable for new 802.3bt deployments. |
Compared with PD69210C-022619, PD69220C-022619 offers superior thermal performance in constrained layouts via LGA mounting and direct PD69200 footprint compatibility, while PD69200C-022619 lacks essential 802.3bt features and scalability - making PD69220C-022619 the sole choice for new high-power, high-port-count designs.

FAQ
What is the package type and thermal specification of PD69220C-022619?
PD69220C-022619 uses a 32-pin laminated QFN (LGA), 5 mm × 5 mm package with an exposed thermal pad (ePAD). Its junction-to-ambient thermal resistance (θJA) is 65.0°C/W, and junction-to-case (θJC) is 21.5°C/W. Proper PCB layout - including ≥4 thermal vias under the ePAD connected to VSSA - is mandatory to maintain thermal integrity and avoid derating.
Does PD69220C-022619 support IEEE 802.3bt and HDBaseT (PoH)?
Yes, PD69220C-022619 fully supports IEEE 802.3bt (including Type 3 and Type 4, up to 90W system-wide) and HDBaseT Power over HDBaseT (PoH) standards. This enables 4-pair power delivery and interoperability with high-power devices such as PTZ cameras, thin clients, and AV transceivers - confirmed in Table 1 of DS00003424D.
How does PD69220C-022619 handle communication with the host processor?
PD69220C-022619 supports either I2C or UART host interfaces, selected via analog voltage on Pin 22 (I2C_ADDR_MEAS). I2C operates at up to 400 kHz with clock stretch support and configurable 7-bit addresses (0x04–0x3C); UART uses fixed 19.2 kbps, 8N1 framing. Both use a deterministic 15-byte protocol for commands and telemetry.
Can PD69220C-022619 replace PD69200 on an existing PCB?
Yes, PD69220C-022619 is explicitly pin-compatible with PD69200 and supports migration from legacy designs. Section 4.6 of DS00003424D provides dedicated PCB layout guidance - including solder mask, top-layer copper, and paste mask patterns - for drop-in replacement without board re-spin.
What power management modes does PD69220C-022619 support?
PD69220C-022619 supports three power management modes: Class (LLDP-based), Dynamic (real-time load monitoring), and Static (fixed allocation). Each mode operates per port, allowing fine-grained control of power budgets across mixed-device deployments - e.g., allocating 15.4W to VoIP phones and 60W to wireless APs within the same switch.
