Product details
Overview
PD69200R-021126 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller implementing IEEE 802.3af, 802.3at, 802.3bt, and HDBaseT PoH standards. It delivers up to 45 W per two-pair port or 90 W per four-pair port, supports 16 power banks across four supplies, and operates in Class, Dynamic, or Static power management modes. It serves as the system-level control unit in multi-port PoE switches and midspans.
For engineers reviewing the PD69200R-021126 datasheet, PD69200R-021126 pinout, PD69200R-021126 application, or PD69200R-021126 equivalent, key selection criteria include IEEE 802.3bt compliance, SPI/I2C/UART host interface flexibility, 32-pin QFN thermal performance, and firmware-upgradable architecture for field deployment in enterprise and industrial PoE infrastructure.
Technical Context
The PD69200R-021126 implements a hierarchical PSE architecture where it acts as the master controller communicating via 1 MHz SPI with up to 12 PD69208T4/PD69204T4/PD69208M PoE managers. Its firmware-pre-programmed and field-upgradeable via I2C or UART-supports both legacy detection and fast/perpetual PoE negotiation sequences.
It integrates dual communication paths: a dedicated ESPI bus (SCK/MOSI/MISO/CS) to PoE managers and a configurable host interface (I2C or UART) selected by analog voltage on pin #22 (I2C_ADDR_MEAS). The controller provides real-time port status, measurements, and interrupt-driven event reporting through xINT_OUT and xI2C_MESSAGE_READY signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
PD69200R-021126 is housed in a 32-pin, 5 mm × 5 mm QFN package with exposed thermal pad (ePAD) requiring connection to VSSA. The package complies with MSL3 and RoHS, and supports Pb-free reflow up to 260 °C peak temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 9, 14, 17–18, 23, 29 | Reserved | Unused pins; specific handling defined per function (e.g., pull-up, connect to 3.3 V/GND, or leave open). |
| 3–6 | ESPI Bus | Chip select (ESPI_xCS), clock (ESPI_SCK), MOSI, MISO: dedicated 1 MHz SPI interface to PoE managers (PD69208T4 etc.). |
| 7, 15 | VDDA / VDD | Analog/digital 3.3 V supply inputs: require local decoupling; VDDA powers analog circuitry including ADCs and reference circuits. |

| 22 | I2C_ADDR_MEAS | Analog input selecting UART vs. I2C mode and setting 7-bit I2C address (0x4 to 0x3C) via external resistor divider. |
| 24–25 | xI2C_MESSAGE_READY / xINT_OUT | Interrupt signaling: active-low flags indicating pending I2C reply or pre-configured system/port events (e.g., overload, disconnect). |
| 26–28 | xLED_CS / xLED_LATCH / xLED_OE | LED stream control: enable, latch, and chip-select outputs for driving multi-segment status LEDs per PoE port. |
| 30 | FAN_CONTROL | Active-high logic output: directly drives fan drivers or PWM controllers for thermal management of PoE power stages. |
| 31 | xDISABLE_PORTS | Active-low global shutdown: asserts low to disable all PoE ports simultaneously for emergency power-off or maintenance. |
| 32 | xSys_OK/LED System OK | System validity indicator: active-low output controlled by software mask; used for chassis-level health monitoring or LED feedback. |
| ePAD | Thermal Pad | Exposed copper pad connected to VSSA: requires ≥65% solder coverage and thermal vias for effective heat dissipation (θJC = 1.8 °C/W). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PoE PSE controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PD69220 | Pin-compatible with identical feature set and IEEE 802.3bt support; newer SAM D21-based silicon with updated firmware stack. | Targeted for new designs only; lacks legacy NXP MKL15Z128VFM4 compatibility layer present in PD69200R-021126. | Select PD69220 for greenfield projects requiring latest firmware features and long-term roadmap alignment. |
| PD69210 | Also SAM D21-based but optimized for lower-cost, lower-port-count systems; supports up to 24 logical ports (vs. 48) and fewer power banks. | Suitable for compact 8–16 port PoE injectors or midspans where full 48-port scalability is unnecessary. | Choose PD69210 when cost sensitivity outweighs need for maximum port density and bank granularity. |

FAQ
What IEEE PoE standards does the PD69200R-021126 support?
The PD69200R-021126 supports IEEE 802.3af (Type 1), 802.3at (Type 2), 802.3bt (Types 3 and 4), and HDBaseT PoH standards. It performs full detection, classification, and maintenance power signature (MPS) for all compliant Powered Devices. This enables interoperability with legacy and next-generation endpoints-including 90 W Type 4 devices-when used with compatible PoE managers like PD69208T4.
How is the host interface (I2C vs. UART) selected on the PD69200R-021126?
The host interface is selected by applying a specific analog voltage to pin #22 (I2C_ADDR_MEAS). An external resistor divider sets the voltage level, which determines both the interface mode (UART or I2C) and the 7-bit I2C address (0x4 to 0x3C). For example, 0.3 V selects UART mode, while 0.5 V configures I2C address 0x4. Full voltage-to-address mapping is provided in Table 1-2 of the datasheet.
Can the PD69200R-021126 be used in a 48-port PoE system?
Yes, the PD69200R-021126 is designed for 48-port systems. It supports cascading up to 12 PoE managers (e.g., PD69208T4) via its dedicated ESPI bus, with each manager controlling four ports. Its 16 power banks distributed across four supplies allow granular power budgeting and fault containment across the full 48-port configuration.
What is the role of the xDISABLE_PORTS pin on the PD69200R-021126?
The xDISABLE_PORTS pin is an active-low input that globally disables all PoE ports when asserted. When pulled low, the PD69200R-021126 shuts down power delivery to every connected port-used for emergency power-off, maintenance mode, or system-level safety interlocks. It requires proper pull-up or driver circuitry per AN3361 guidelines.
Does the PD69200R-021126 support firmware updates in the field?
Yes, the PD69200R-021126 supports field firmware upgrades via its I2C or UART interface using the 15-byte protocol. Firmware is pre-programmed at factory but can be updated post-deployment to add features, fix bugs, or adapt to new standards-eliminating the need for hardware revisions in deployed systems.
