Product details

Overview

PD69200R-017217 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 via cascaded PoE managers. It integrates NXP MKL15Z128VFM4-based firmware, supports 45 W two-pair and 90 W four-pair per port, operates from a 3.3 V supply, and resides in a 32-pin 5 mm × 5 mm QFN package. It serves as the central intelligence layer in enterprise switches, IP phone hubs, and network video recorders requiring multi-port PoE classification and dynamic power allocation.

For engineers reviewing the PD69200R-017217 datasheet, PD69200R-017217 pinout, PD69200R-017217 application, or PD69200R-017217 equivalent, key selection criteria include IEEE 802.3bt compliance, SPI/I2C/UART host interface flexibility, 32-pin QFN thermal performance (θJA = 33 °C/W), interrupt-driven event reporting (xINT_OUT), and firmware-upgradable architecture supporting field updates via I2C or UART.

Technical Context

The PD69200R-017217 implements a hierarchical PSE control architecture: it communicates with up to 12 PoE manager ICs (e.g., PD69208T4) via 1 MHz SPI to orchestrate port detection, classification, power-up sequencing, and real-time monitoring. Its embedded firmware supports three power management modes-Class (LLDP), Dynamic, and Static-and enables 16 independent power banks across four external supplies.

Hardware-level interfaces include dual communication paths (I2C at 400 kHz with clock stretch support, UART at 19.2 kbps), dedicated LED stream control (xLED_CS/xLED_LATCH/xLED_OE), system status signaling (xSys_OK), and hardware port disable (xDISABLE_PORTS). All digital I/O operates at 3.3 V with ESD immunity of ±2000 V HBM and ±500 V CDM.

Key Specifications

Pinout & Package

PD69200R-017217 is housed in a RoHS-compliant, moisture-sensitivity level 3 (MSL3), 32-pin plastic QFN package measuring 5 mm × 5 mm with an exposed thermal pad (ePAD) that must be connected to VSSA for thermal integrity.

Pin/Terminal	Circuit Role	Design Meaning
1–2, 9, 13–14, 17–18, 23, 29	Reserved	Unused pins; specific configurations require leaving open, pulling to 3.3 V, or grounding per AN3361 - no user functionality.

20 (I2C0_SCL), 21 (I2C0_SDA)	I2C Host Interface	400 kHz bidirectional bus with mandatory clock stretch support - allows low-overhead host polling and event-driven reads.
22 (I2C_ADDR_MEAS)	Analog Address Selection	Voltage-level programmed I2C address (0x4 to 0x3C) or UART mode selection - eliminates external address jumpers.
24 (xI2C_MESSAGE_READY)	I2C Message Ready Flag	Active-low handshake indicating valid reply data is available - eliminates polling overhead and improves host efficiency.
25 (xINT_OUT)	System/Port Interrupt Output	Active-low assertion on preconfigured events (e.g., port fault, overtemp, classification failure) - enables immediate host response.
26–28 (xLED_CS, xLED_LATCH, xLED_OE)	LED Stream Control	Three-signal interface driving multiplexed status LEDs per port - reduces GPIO count and simplifies front-panel design.
30 (FAN_CONTROL)	Fan Driver Logic Output	Active-high signal for thermal management - directly drives fan controllers or optocouplers without external logic.
31 (xDISABLE_PORTS)	Global Port Disable Input	Active-low hardware kill switch - immediately shuts down all PoE ports for safety or maintenance without firmware involvement.
32 (xSys_OK/LED System OK)	System Validity Indicator	Active-low output reflecting firmware health and power rail integrity - configurable via software mask for custom fault conditions.

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; newer firmware stack.	Recommended for all new designs; supports same 48-port cascade and 90 W per port but with updated peripheral drivers.	Select PD69220 for greenfield projects requiring long-term roadmap alignment and extended firmware support.
PD69210	Based on Microchip SAM D21; lacks 48-port cascade capability (max 24 logical ports); same 90 W per port and IEEE 802.3bt compliance.	Targeted at cost-sensitive, lower-port-count applications such as 8- or 16-port desktop switches.	Choose PD69210 when port count ≤24 and BOM cost optimization outweighs scalability needs.

Compared with PD69200R-017217, PD69220 offers identical pinout and features with modernized firmware and longer product lifecycle, while PD69210 trades cascade depth for reduced silicon cost - making PD69200R-017217 the optimal choice for sustaining existing 48-port designs requiring drop-in replacement.

Yes, PD69200R-017217 is pin-compatible with PD69220, sharing identical 32-pin QFN layout, pin functions, and electrical characteristics. This allows direct PCB reuse in legacy designs transitioning to newer firmware platforms. PD69210 shares core functionality but differs in pin assignment and lacks full 48-port cascade support.

How is firmware updated on PD69200R-017217?

Firmware on PD69200R-017217 is field-upgradable via its I2C or UART interface using Microchip's provided Serial Communication Protocol. The controller accepts 15-byte command packets for profile modification, parameter tuning, or full firmware replacement - no JTAG or external programmer required.

What thermal performance can be expected from PD69200R-017217 in a 5 mm × 5 mm QFN package?

PD69200R-017217 achieves θJA = 33 °C/W and θJC = 1.8 °C/W when mounted on a standard 4-layer PCB with the ePAD soldered to a solid VSSA copper plane. This enables continuous operation at full 48-port load in ambient temperatures up to 85 °C, provided minimum 65% thermal pad coverage and proper via placement per AN3361 guidelines.

Does PD69200R-017217 support LED status indication for individual PoE ports?

Yes, PD69200R-017217 integrates native LED stream control via xLED_CS, xLED_LATCH, and xLED_OE pins. These signals drive daisy-chained LED drivers to display per-port status (e.g., link, activity, power state) without consuming host GPIO resources - reducing firmware overhead and simplifying front-panel design.
