PD70200ILD-TR Visão geral
A PoE PD interface controller is the analog front end that sits between a Power Sourcing Equipment (PSE) device, such as a network switch, and the powered electronics at the far end of the Ethernet cable. Within the power management IC hierarchy, it performs input rectification control, detection, classification, inrush current limiting, and disconnect identification so the PSE can safely deliver power over the same twisted-pair cabling that carries data.
Key features include full IEEE 802.3at (PoE+) and 802.3af (PoE) compliance, dual-event classification detection for Type 2 power negotiation, PGOOD status indication, overcurrent protection, and thermal protection. The integrated 0.6 ohm MOSFET eliminates an external pass device, reducing board area and Bill of Materials cost compared with discrete controller-plus-FET solutions.
Architecturally, the PD70200 transmits integrated power and analog status data through a single 12-pin package, handling the IEEE 802.3af/at detection signature (25.5 kohm), class marking, and inrush management autonomously. Its wide 0V to 57V supply range tolerates the full PoE+ PSE voltage envelope, while the low 1 mA operating supply current keeps standby losses minimal.
Typical applications include IP security cameras, wireless access points, VoIP phones, and networked LED lighting drivers that must draw power directly from the Ethernet cable. The device is equally suitable for industrial PoE sensors and building-automation endpoints.
For design, ensure the thermal pad is well soldered to the PCB copper pour, since the internal FET dissipates conduction losses proportional to I2 x 0.6 ohm at full 48W load.

Aplicações típicas
PD70200ILD-TR é adequado para 6 aplicaçãos: IP Security Cameras, Wireless Access Points, VoIP Phones, Networked LED Lighting, Industrial PoE Sensors and Building Automation, Network Video Recorders and PoE Splitter Modules.
IP Security Cameras
IP surveillance cameras are the classic PoE powered device: a single Cat5e cable delivers both data video streams and DC power. The PD70200ILD-TR fits this role because its integrated 0.6 ohm pass FET and full IEEE 802.3af/at signature, dual-event classification, and inrush control let a 48W PoE+ budget reach the camera without any discrete power-negotiation circuitry. In a typical circuit the PD70200 sits directly behind the Ethernet transformer and diode bridges; its PGOOD output gates the camera SoC power rail so boot-up only begins after valid PSE power is negotiated. Because PTZ cameras with IR illuminators and heaters can consume most of a 25.5W Type 2 allocation, designers should budget current against the classified class and rely on the PD70200's overcurrent and thermal protection as the last line of defense against cable faults.

Wireless Access Points
Enterprise and mesh Wi-Fi access points typically draw 15W to 30W, exactly the envelope the PD70200ILD-TR negotiates under IEEE 802.3at. Its 0V to 57V input tolerance handles the full PSE voltage range, while dual-event classification ensures a Type 2 PSE delivers the full PoE+ allocation after two classification events, as the standard requires. In an access point board, the PD70200 is placed between the RJ45 magnetics and the DC-DC converters that generate the radio and SoC rails; the internal 0.6 ohm FET keeps interface losses to roughly 0.15W at 0.5A, preserving thermal margin in sealed enclosures. PGOOD sequencing allows the main regulator to enable only after inrush settling, protecting the radio PA from brown-out. The 1 mA controller supply current also helps compliance with the low-power idle modes modern AP firmware uses.
Recomendado
VoIP Phones
VoIP desk phones are mandated in many deployments to be powered solely from the Ethernet cable under IEEE 802.3af, and the PD70200ILD-TR implements the complete required PD interface: the 25.5 kohm detection signature, class marking, inrush limiting, and disconnect identification. Its single-chip integration - pass FET included in the 4x3 mm DFN - suits the dense, cost-sensitive layout inside a phone base, replacing a controller plus external MOSFET. During PoE negotiation the PGOOD output sequences the phone's main DC-DC converters so the DSP boots only after stable PSE power, avoiding the audible pops and reboots that poor sequencing causes. With 1 mA controller quiescent current, standby draw stays low enough to keep the endpoint within the class power the PSE reserved. Thermal protection guards against sustained fault currents on long cable runs.

Networked LED Lighting
PoE-connected LED luminaires and smart-building lighting nodes use the Ethernet cable for both control data (DALI-like or proprietary protocols) and LED string power, frequently at the 25.5W PoE+ level that the PD70200ILD-TR supports. The device's 48W capability and dual-event classification let the luminaire advertise a Type 2 class so the switch reserves sufficient power, while the integrated 0.6 ohm FET minimizes interface loss - important because luminaires are sealed with limited convective cooling. Placed after the RJ45 magnetics, the PD70200 feeds the LED driver stage; PGOOD ensures the driver enables only after negotiation completes, preventing visible flicker during plug-in. Overcurrent and thermal protection protect the fixture against shorted wiring in ceiling installations where service access is difficult. The 0V to 57V input range accommodates all PSE voltage variants.

Industrial PoE Sensors and Building Automation
Factory-floor sensors, access-control readers, and building-automation endpoints increasingly adopt PoE to eliminate separate power wiring in difficult-to-cable locations. The PD70200ILD-TR suits these nodes because it tolerates the harsh electrical environment of long structured cabling: its 0V to 57V input span and integrated overcurrent, thermal, and disconnect-identification protection handle cable faults, PSE reboots, and hot-plug events without external supervisory circuitry. The 12-DFN exposed-pad package solders its thermal path directly to the control board, and the 1 mA operating current keeps small, battery-backup-supported sensors within their energy budgets. In a typical node, the PD70200 sits between the magnetics and the node's DC-DC stage; PGOOD sequences the microcontroller so it never operates from an unclassified PSE connection. Dual-event classification enables 48W nodes such as motor-actuated dampers.

Network Video Recorders and PoE Splitter Modules
PoE splitter and midspan-derived power modules, including those inside NVR accessory cameras and legacy-device adapters, need a compact PD front end that extracts up to 48W from a PoE+ port and hands it to a downstream regulator. The PD70200ILD-TR is a strong fit: its integrated 0.6 ohm FET and complete IEEE 802.3af/at handshake fit within the small PCB area of a splitter enclosure, and the 12-pin DFN's exposed pad simplifies thermal design in enclosed plastic housings. Because splitters are frequently hot-plugged into live switch ports, the PD70200's controlled inrush and disconnect identification prevent the PSE from tripping on connection transients - a common field failure for cheaper discrete implementations. Its PGOOD output drives the downstream buck converter enable pin, guaranteeing clean output rails only after a valid power contract exists.

Notas de projeto
Estimated: at full PoE+ load of about 0.55 A through the internal 0.6 ohm FET, conduction loss is I^2 x R = 0.18 W - easily handled by the exposed pad, but dissipation rises at lower PD input voltage on long cable runs. Solder the 12-DFN exposed pad to at least 1 square inch of 2 oz copper pour with an array of thermal vias. Verify junction temperature against the datasheet derating curve at your minimum expected PD input voltage, not just nominal 48V.
Keep the loop between the Ethernet transformer center taps, input diode bridges, bulk capacitor, and the PD70200 VDD/RTN pins short and wide to limit surge voltage spikes during PSE voltage application. Place the classification and detection programming resistors close to their pins and away from the high-current FET path to avoid resistive heating errors. The PGOOD output should route to the enable pin of the downstream DC-DC converter with a pull-up to a stable low-voltage rail.
Do not omit the bulk input capacitance specified in the Microchip application circuit - insufficient capacitance causes the PSE to see excessive inrush and refuse power. Remember that the device is documented under both Microsemi and Microchip branding (datasheet DS00003639B); ensure you buy Microchip-sourced production parts. Also confirm your downstream DC-DC converter tolerates the full 0V-to-57V input envelope during detection phases when the line voltage is unregulated.
