PD69220C-022419 개요
A Power over Ethernet (PoE) controller is a specialized mixed-signal IC inside an Ethernet switch that orchestrates detection, classification, power-up, and disconnection of Powered Devices (PDs) over the spare or data pairs of an Ethernet cable. It sits within the power-management IC (PMIC) hierarchy as part of a PoE subsystem, which combines an MCU-style digital controller (PD69220) with one or more analog manager ICs (PD69208x) for current sense and MOSFET gate driving. The combined PSE subsystem complies with IEEE 802.3af, IEEE 802.3at (PoE+), IEEE 802.3bt, and the PoH standard.
Key features of the PD69220C-022419 variant include a 32-LGA 5x5 mm footprint compatible with the older PD69200, an ESPI (Enhanced Serial Peripheral Interface) link to the host switch CPU, an integrated firmware image (v2.24.19) that supports legacy PD detection plus Auto and High-power classes, and preloaded algorithms for inrush management, AC/DC disconnect detection, and per-port current limiting. Per-port controlled outputs are managed through the companion PD69208T4 / PD69204T4 managers, not directly by this MCU.
Architecturally, the PD69220 is built around an embedded 8-bit MCU core with mask/firmware storage and digital I/O for host communication. The firmware image selected at order time (here, v2.24.19) defines port count support, classification behavior, and other behaviors. Designers can upgrade via later firmware versions such as PD69220C-022419 and PD69220C-022319 by re-spinning a board if the LGA footprint matches.
Typical applications include managed enterprise Ethernet switches with PoE+ ports, 802.3bt Type-3/Type-4 PSE midspans and endspans, indoor/outdoor wireless access points, IP surveillance cameras powered over Ethernet, and industrial Ethernet switches that feed Class-8 PoH loads. Designers choose it when they need up to 48 PoE channels controlled by one MCU with a single firmware SKU.
For layout, place the 32-LGA thermal pad over a ground pour to dissipate the small controller self-heating. Provide a clean 3.3 V rail and route the ESPI bus as short as possible to the host processor; longer traces should be impedance-controlled.

일반적인 애플리케이션
PD69220C-022419 적합 용도: 6 애플리케이션s: Enterprise PoE+ Ethernet Switches, IEEE 802.3bt Type-3 / Type-4 Midspans, Wireless Access Point Power Distribution, IP Surveillance Camera Networks, Industrial PoE Switches, PoH (Power over HDBaseT) Enabled Switches.
Enterprise PoE+ Ethernet Switches
The PD69220C-022419 is a natural fit for managed enterprise Ethernet switches with up to 48 PoE+ ports. It connects to the host CPU through ESPI and orchestrates detection, classification, and power-up of each Powered Device per IEEE 802.3at, while the companion PD69208T4 managers handle the per-port current sense and MOSFET gate driving. With firmware v2.24.19, it supports both 2-pair and 4-pair power delivery up to Type-4 (90 W) levels, allowing one MCU to control an entire 24- or 48-port switch line without software re-spin. The 32-LGA 5x5 mm footprint keeps the digital section compact, leaving front-panel PCB area for magnetics and PSE channels.

IEEE 802.3bt Type-3 / Type-4 Midspans
In midspan injectors that add PoE to existing non-PoE switches, the PD69220C-022419 sits at the heart of the power controller subsystem and supervises detection of PDs before applying 802.3bt power. Its firmware v2.24.19 supports the high-power Type-3 (60 W) and Type-4 (90 W) classes required by modern PTZ cameras, Wi-Fi 6E access points, and LED lighting fixtures. Pairing with PD69208T4 managers gives a typical midspan 8 to 24 powered ports while keeping the controller 32-LGA footprint compatible with midspan hardware. Designers benefit from the pre-programmed firmware that handles all required LLDP-based power negotiation sequences out of the box.

Wireless Access Point Power Distribution
Wireless access points - especially Wi-Fi 6E and Wi-Fi 7 indoor and outdoor models - are increasingly PoE-powered and often demand 802.3bt Class-5 or Class-6 power, well within the PD69220C-022419's firmware v2.24.19 capabilities. In a switch feeding the APs, this controller delivers per-port power management with AC and DC disconnect detection, eliminating the need for an external PoE MCU. Combined with a PD69208T4 manager it allows a single PSE channel per AP and supports the 2.5 GbE and 5 GbE data rates that modern APs require, while the controller's 32-LGA footprint occupies minimal board area in space-constrained switch designs.
추천
IP Surveillance Camera Networks
Large camera deployments power each IP camera over Ethernet, often with PTZ heaters, IR illuminators, or pan-tilt motors that exceed simple PoE+ budgets. The PD69220C-022419 firmware v2.24.19 supports 802.3bt high-power classes that deliver 60 W or 90 W per port, covering most PTZ camera power needs. The controller handles legacy detection (to avoid damaging non-PoE devices), 4-event classification, and AC/DC disconnect, all important for outdoor cameras that cycle power frequently. In a typical 24-port NVR switch, two PD69208T4 managers pair with one PD69220C-022419 to deliver per-port power management without firmware changes.
추천
Industrial PoE Switches
Industrial Ethernet switches for factory automation often need -40 C to +85 C operation and high reliability over long cable runs. The PD69220C-022419 in industrial-grade qualification grades supports that envelope while exposing the same ESPI host interface as the commercial version. With one MCU and one or more PD69208T4 managers, a switch can deliver PoE to IP67 I/O blocks, machine-vision cameras, and AGV charging stations. Designers reuse the same 32-LGA footprint for both commercial and industrial SKUs, simplifying the BOM between temperature grades and lowering second-source risk.
추천
PoH (Power over HDBaseT) Enabled Switches
Power over HDBaseT (PoH) uses the same 4-pair powering concept as 802.3bt but with vendor-specific extensions for AV distribution; the PD69220C-022419 firmware v2.24.19 explicitly supports PoH alongside IEEE 802.3bt. In an AV-over-IP or HDBaseT distribution switch, this controller detects HDBaseT endpoints and delivers up to 100 W over a single cable run. Because the PoE controller sits in the digital domain and the PD69208x managers handle the per-pair current sense, the same PCB layout supports both standard PoE loads and HDBaseT endpoints with no firmware rewrite on the MCU.

설계 노트
Estimated: Place the 32-LGA thermal pad over a continuous ground pour with at least 4 thermal vias (8 mil diameter) to the inner ground plane. Route the ESPI bus as short as possible to the host CPU; ESPI traces longer than 25 mm should be impedance-controlled at 50 ohms to single-end ground, with a guard ground on each side. Decouple VDD and VDDIO with 100 nF + 10 uF ceramic capacitors placed within 2 mm of each supply pin.
Estimated: Keep the MGMT_CLK, MGMT_DATA, and MGMT_EN lines between the PD69220C and the PD69208T4/PD69204T4 managers to within 50 mm total length. Use a 4-layer stackup with the second layer as a solid ground plane; the third layer should carry 3.3 V power, and the top/bottom layers should be dedicated to signal routing. This stackup minimizes the EMI that PoE switching transients inject into the analog sense paths.
Do not attempt to drive the Ethernet pairs directly from the PD69220C-022419 - it has no per-port analog drivers. Always pair the MCU with at least one PD69208M, PD69208T4, or PD69204T4 manager; without one the controller cannot deliver power. Also note: firmware revisions in the same PD69220C family (for example C-022419 vs C-022319) are not interchangeable on the fly - they require reflashing via the host CPU before the change takes effect.
규정 준수 정보
RoHS and lead-free per Microchip product page conventions for the PD692xx family; AEC-Q100 not applicable since this is a PoE controller MCU, not an automotive analog IC; halogen-free and full conflict-minerals declarations should be requested from Microchip if your procurement policy requires them.
