Product details
Overview
PD69200C-016721 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC designed for IEEE 802.3af/at/bt and HDBaseT (PoH) compliant systems. It integrates with PD69208T4/PD69204T4/PD69208M PoE managers, supports up to 48 logical ports via cascading, delivers up to 90 W per four-pair port, and operates in a 32-pin 5 mm × 5 mm QFN package rated for –40 °C to +85 °C ambient.
For engineers reviewing the PD69200C-016721 datasheet, PD69200C-016721 pinout, PD69200C-016721 application, or PD69200C-016721 equivalent, key selection criteria include IEEE 802.3bt compliance, SPI/I2C/UART host interface flexibility, 16-power-bank architecture, fast/perpetual PoE support, and firmware-upgradability via serial interfaces.
Technical Context
The PD69200C-016721 implements a hierarchical PSE control architecture: it communicates with PoE manager ICs (e.g., PD69208T4) via 1 MHz SPI slave interface while supporting independent host control via UART (19.2 kbps) or I2C (400 kHz with clock stretch). Its firmware-pre-programmed and field-upgradable-enables three power management modes (Class, Dynamic, Static) and full port-level status monitoring including legacy detection and LED stream control.
Based on the NXP MKL15Z128VFM4 microcontroller core, the PD69200C-016721 provides integrated analog sensing (VDDA, VAIO), digital I/O (xINT_OUT, xDISABLE_PORTS, xSys_OK), and configurable communication interface selection (via I2C_ADDR_MEAS pin voltage), enabling flexible integration into enterprise switches, IP phone infrastructure, and smart building PoE systems without requiring external microcontrollers.

FAQ
What IEEE PoE standards does the PD69200C-016721 support?
The PD69200C-016721 supports IEEE 802.3af (Type 1), 802.3at (Type 2), 802.3bt (Types 3 and 4), and HDBaseT (PoH) standards. It performs full signature detection, classification, and power delivery per port, including legacy device detection. This enables interoperability with a broad range of powered devices from VoIP phones to 90 W PTZ cameras. The PD69200C-016721 firmware implements all required physical layer timing and safety checks defined in Clause 33 and Clause 145 of IEEE Std 802.3-2018.
How is host communication configured on the PD69200C-016721?
Host communication on the PD69200C-016721 is selected via the I2C_ADDR_MEAS pin (Pin 22): applying specific voltage levels sets either UART or I2C mode and determines the 7-bit I2C address (0x04 to 0x3C). UART operates at 19.2 kbps (8N1), while I2C runs at up to 400 kHz with mandatory clock stretch support. Both interfaces use a standardized 15-byte protocol for commands and telemetry. The PD69200C-016721 can operate stand-alone or under host control - no external microcontroller is required for basic operation.
Can the PD69200C-016721 be used in a cascaded PoE system?
Yes, the PD69200C-016721 supports cascading up to 12 PoE controller ICs to manage 48 logical ports. It communicates with PD69208T4, PD69204T4, or PD69208M PoE managers via a dedicated 1 MHz SPI bus (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO). Each manager handles up to four ports, and the PD69200C-016721 coordinates power allocation, priority, and fault reporting across the entire chain. This architecture eliminates the need for multiple independent controllers in high-port-count switches.
What are the thermal requirements for the PD69200C-016721?
The PD69200C-016721 has a junction-to-ambient thermal resistance (θJA) of 33 °C/W and junction-to-case (θJC) of 1.8 °C/W. Its 5 mm × 5 mm QFN package includes an exposed thermal pad (ePAD) that must be soldered to a VSSA-connected copper plane with thermal vias. Recommended reflow peak temperature is 260 °C (40 s max), and the device is MSL3 rated. For sustained 90 W operation across multiple ports, PCB layout must provide ≥4 cm² of 2-oz copper connected to the ePAD with ≥6 thermal vias (0.3 mm diameter).
Is firmware upgrade supported on the PD69200C-016721 after deployment?
Yes, the PD69200C-016721 supports field firmware upgrades via its UART or I2C interface using the same 15-byte protocol used for runtime commands. Firmware images are delivered as binary payloads and validated before execution. Upgrade capability allows end users to add new features (e.g., enhanced diagnostics), fix bugs, or adapt to evolving PoE standards without hardware modification. The PD69200C-016721 ships with pre-programmed firmware; revision details are encoded in the part number suffix (e.g., "C-016721" indicates firmware version C and parameter set 016721).
