MP8007GV-Z Обзор
A PoE PD interface is the circuit block inside a powered device - such as an IP camera, wireless access point, or VoIP phone - that negotiates and safely draws power from the Ethernet cable according to the IEEE 802.3af/at standard. It sits at the top of the power-management hierarchy: PoE PD interface -> hot-swap/power-switch IC -> power management IC -> semiconductor. The PD interface performs detection, classification, and controlled inrush before handing power to the downstream DC-DC converter stage.
The MP8007 integrates all IEEE 802.3af/at required functions: signature detection, classification, a 120mA inrush current limit, an 840mA operating current limit, and an internal 100V-rated hot-swap MOSFET. Integrating the MOSFET eliminates an external pass device, reducing BOM count and board area compared with two-chip PD interface plus MOSFET solutions.
The integrated DC-DC converter uses fixed peak-current-mode control, supporting both isolated (flyback) and non-isolated (buck) topologies targeted at 13W PoE applications. This single-chip approach simplifies magnetics selection and loop compensation for mid-power powered devices.
Typical applications include IP surveillance cameras, IEEE 802.11 wireless access points, VoIP telephones, network-attached IoT gateways, and industrial Ethernet endpoints powered entirely over the data cable.
Design consideration: verify the input diode bridge and transient suppression ahead of the PD interface survive the 100V backfeed and surge events defined by IEEE 802.3af/at; the internal 100V hot-swap MOSFET provides margin but the front-end passives must be rated accordingly.

Типичное применение
MP8007GV-Z подходит для 6 применениеs: IP Surveillance Cameras, Wireless Access Points, VoIP Telephones, IoT Gateways and Network Sensors, Building Automation and Access Control, Non-Isolated PoE Splitter Modules.
IP Surveillance Cameras
The MP8007GV-Z fits IP camera designs because 13W covers the power budget of a mainstream network camera including image sensor, ISP/SoC, IR-LED array, and pan-tilt mechanics without requiring a local power adapter. The integrated PD interface handles IEEE 802.3af/at detection, classification, and the 120mA inrush limit, so the camera can be powered from any compliant PoE switch over the single Ethernet cable. The integrated 100V hot-swap MOSFET tolerates cable transients, and the fixed peak current mode converter supports either an isolated flyback (for multi-rail cameras needing separate sensor and LED supplies) or a non-isolated buck for single-rail designs. The 840mA operating current limit keeps the design within standard current envelopes at full IR-LED load.

Wireless Access Points
IEEE 802.11 wireless access points are classic 13W-class powered devices, making the MP8007GV-Z a strong fit: the MPS datasheet explicitly targets the part at isolated or non-isolated 13W PoE applications, which matches the typical draw of a dual-band access point with a multi-core SoC and RF front ends. The integrated PD interface performs all 802.3af/at detection and classification functions, while the fixed peak current mode converter steps the nominal 48V input down to 5V or 12V intermediate rails for the radio and processor stages. The 100V integrated hot-swap MOSFET removes the external pass transistor, shrinking PCB area in the compact AP form factor, and the 840mA limit aligns with cable-current constraints.

VoIP Telephones
VoIP desk phones are the archetypal IEEE 802.3af Class 2/3 powered device, drawing well within the MP8007GV-Z's 13W target for the handset SoC, display, and Ethernet switch ports. The integrated detection and classification circuitry ensures the phone presents a valid 802.3af signature to the PBX-side PoE switch and negotiates the correct power class automatically. Because the MP8007 integrates the 100V hot-swap MOSFET with a 120mA inrush limit, the phone hot-plugs safely into live network jacks without external protection MOSFETs. The fixed peak current mode converter supports a simple non-isolated buck topology for the phone's single 5V/3.3V rail set, minimizing cost in high-volume enterprise telephony deployments.

IoT Gateways and Network Sensors
Industrial IoT gateways and networked sensor nodes benefit from the MP8007GV-Z because single-cable power plus data removes the need for local AC wiring in ceiling, wall, or field installations. At 13W, the part powers an ARM-based gateway SoC, radios, and sensor front ends. The PD interface implements every IEEE 802.3af/at required function - detection, classification, inrush control, and current limiting - so the node interoperates with standard enterprise PoE switches. The integrated 100V hot-swap MOSFET provides margin against cable surges in long building runs, and the converter's isolated flyback support enables designs where field wiring isolation is required. The 28-QFN (4x5 mm) package suits compact DIN-rail and enclosure-mounted gateway hardware.

Building Automation and Access Control
Door controllers, card readers, and building automation controllers increasingly adopt PoE to eliminate dedicated power drops. The MP8007GV-Z's 13W budget covers the controller MCU, RFID/NFC reader front end, relays, and indicators typical of these nodes. Its IEEE 802.3af/at PD interface - with signature detection, classification, 120mA inrush, and 840mA operating current limit - ensures reliable interoperability with structured-cabling PoE switches from any vendor, a requirement in multi-vendor building installations. The 100V integrated hot-swap MOSFET withstands the transients common in long horizontal cable runs, and the choice between isolated and non-isolated converter topologies lets designers match the isolation requirements of door-strike and reader circuits while keeping BOM count low.

Non-Isolated PoE Splitter Modules
Compact PoE splitter modules that deliver 5V or 12V auxiliary output to non-PoE end devices are a natural application for the MP8007GV-Z. The part's single-chip integration of the PD interface and fixed peak current mode converter controller lets a splitter fit within the small PCB area of an in-line adapter housing, with no external hot-swap MOSFET required thanks to the integrated 100V device. Detection and classification per IEEE 802.3af/at guarantee the splitter draws power correctly from any standard PSE, while the 120mA inrush limit prevents startup disturbances on the Ethernet cable. The non-isolated buck topology keeps component count and magnetics size minimal, directly reducing the module's cost and height profile.

Заметки по проектированию
The MP8007's PD interface enforces IEEE 802.3af/at sequencing: detection, classification, and a 120mA inrush limit before full-power operation at the 840mA limit. Do not place bulk capacitance directly on the VDD line beyond what the standard allows - excess capacitance after the diode bridge can extend inrush beyond the classified timeframe and cause the PSE to disconnect the port. Follow the MPS datasheet typical application circuit for input capacitor placement relative to the hot-swap MOSFET.
At 13W from a nominal 48V PoE input, front-end diode bridges dissipate meaningful power; estimate conduction loss as 2 x Vf x Iavg and select low-Vf Schottky diodes to preserve efficiency. The internal 100V hot-swap MOSFET is rated above the 802.3af/at backfeed requirement, but verify total front-end component voltage ratings, including bridge diodes and transient suppressors, cover surge events specified in the standard.
Place the converter power loop (transformer/inductor, sense resistor, and the MP8007's switching pins) as compact as possible to minimize radiated EMI - important because the same cable carries Ethernet data. Use a solid ground plane under the 28-QFN (4x5 mm) exposed pad and solder it to the PCB for thermal dissipation of the internal hot-swap MOSFET and converter losses. Keep classification and detection sense lines away from switch-node traces to avoid false detection.
