Product details
Overview
PD69200C-022319-TR from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC designed to manage IEEE 802.3af/at/bt and HDBaseT PoH compliant power delivery across up to 48 logical ports when paired with PD69208T4, PD69204T4, or PD69208M managers. It implements port matrix control, dynamic/static/class-based power management, and supports up to 90 W per four-pair port. It operates in industrial temperature range (–40 °C to +85 °C) and integrates UART/I2C host interfaces for firmware updates and telemetry.
For engineers reviewing the PD69200C-022319-TR datasheet, PD69200C-022319-TR pinout, PD69200C-022319-TR application, or PD69200C-022319-TR equivalent, key selection considerations include its 32-pin QFN package, 400 kHz I2C with clock stretch support, 19.2 kbps UART interface, 3.3 V supply operation, and compatibility with Microchip's PoE manager family for scalable multi-port PSE systems.
Technical Context
The PD69200C-022319-TR implements a firmware-driven PSE control architecture based on the NXP Kinetis® L MKL15Z128VFM4 core, enabling standalone or host-coordinated operation via UART or I2C. It communicates with PoE managers (e.g., PD69208T4) using a 1 MHz SPI slave interface with 15-byte packet protocol and supports up to 12 cascaded managers for 48-port scalability.
It features dual-mode detection (IEEE 802.3 + pre-standard), legacy device support, fast/perpetual PoE modes, and hardware-assisted LED stream control via xLED_CS/xLED_LATCH/xLED_OE pins. System-level functions include port priority assignment, 16-power-bank allocation, and interrupt-driven event reporting via xINT_OUT and xSys_OK/LED signals.

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; based on Microchip SAM D21 instead of NXP Kinetis L; newer firmware baseline (P3.xx). | Targeted for new designs requiring latest 802.3bt/PoH firmware and ARM Cortex-M0+ architecture. | Select PD69220 for greenfield projects needing extended lifecycle support and updated toolchain compatibility. |
| PD69210 | Also SAM D21-based; supports same standards but lacks pin compatibility with PD69200; different package and pinout. | Used in space-constrained or cost-optimized PSE designs where layout redesign is acceptable. | Choose PD69210 only when board redesign is feasible and SAM D21 ecosystem alignment is prioritized over drop-in replacement. |

FAQ
What is the primary function of the PD69200C-022319-TR in a PoE system?
The PD69200C-022319-TR serves as the central Power Sourcing Equipment (PSE) controller in IEEE 802.3af/at/bt and HDBaseT PoH systems. It manages power negotiation, classification, fault detection, and port control for up to 48 logical ports when interfaced with PD69208T4, PD69204T4, or PD69208M PoE managers. Its role includes enforcing power budgets, handling legacy detection, and providing telemetry via UART/I2C - making PD69200C-022319-TR essential for compliant, scalable PoE infrastructure.
Does the PD69200C-022319-TR support firmware updates in the field?
Yes, the PD69200C-022319-TR supports field-upgradable firmware via its UART or I2C interface using Microchip's 15-byte communication protocol. Firmware updates enable new feature activation, bug fixes, and compliance extensions for evolving IEEE standards - all without hardware modification. The PD69200C-022319-TR ships with pre-programmed firmware (version indicated by part number suffix), and users can download updated binaries from Microchip's software library to maintain PD69200C-022319-TR in production systems.
How does the PD69200C-022319-TR handle power management across multiple ports?
The PD69200C-022319-TR implements three configurable power management modes - Class (LLDP), Dynamic, and Static - allowing precise allocation of up to 90 W per four-pair port. It supports 16 independent power banks fed by up to four supplies, enabling granular budgeting across port groups. Port priority, cascade topology (up to 12 managers), and real-time current/voltage measurements allow PD69200C-022319-TR to enforce safety limits and optimize total system efficiency without manual recalibration.
What are the key interface requirements for connecting a host processor to the PD69200C-022319-TR?
A host processor connects to the PD69200C-022319-TR via either UART (19.2 kbps, 8N1, pull-up required on RX) or I2C (7-bit address, 400 kHz, clock stretch mandatory). Pin #22 (I2C_ADDR_MEAS) selects the interface mode and sets the I2C address via voltage divider. The host must implement Microchip's 15-byte serial protocol for configuration, telemetry, and event handling - and PD69200C-022319-TR provides xI2C_MESSAGE_READY and xINT_OUT signals to coordinate timing and fault response.
Is the PD69200C-022319-TR pin-compatible with any other Microchip PSE controllers?
Yes, the PD69200C-022319-TR is pin-compatible with the PD69220, sharing identical pinout, package (32-pin QFN), and feature set. This allows direct substitution in existing layouts when upgrading to the newer SAM D21-based controller. However, it is not pin-compatible with PD69210, which uses a different package and pin assignment. For legacy design continuity, PD69200C-022319-TR remains the only drop-in replacement option among Microchip's PD692xx family.
