MP8007 The Future of Analog IC Technology Fully-Integrated 802.3af-Compatible PoE PD Interface with 13W Primary-side Regulated Flyback or Buck Converter DESCRIPTION FEATURES The MP8007 is an integrated IEEE 802.3af compatible PoE Powered Device with PD interface and power converter. It is targeted for isolated or non-isolated 13W PoE application.         The PD interface has all the functions of IEEE 802.3af, including detection, classification, 120mA inrush current, 840mA operation current limit as well as 100V Hot-swap MOSFET. The DCDC converter uses fixed peak current and variable frequency discontinuous conduction mode (DCM) to regulate constant output voltage. The primary-side regulation without opto-coupler feedback in flyback mode simplifies the design while buck mode continues minimizes the solution size for nonisolated applications. A 180V integrated power MOSFET optimizes the device for various wide voltage applications. The MP8007 features protection including over current protection, over voltage protection, open circuit protection and thermal shutdown. The MP8007 can support a front-end solution for PoE-PD application with minimum external component, it is available in QFN-28 (4mmX5mm) package.      Compatible with 802.3af Specifications Support 13W PoE Power Application 100V 0.48Ω PD Integrated Pass Switch 120mA PD Inrush Current 840mA PD Operation Current Limit Auxiliary Adaptor ORing Power Supply Integrated 180V Switching Power MOSFET Supports Primary-Side Regulated Flyback without Opto-Coupler Feedback Supports Low-side Switch Buck Converter Up to 3A Programmable Switching Current Limit OLP, OVP, Open-Circuit, and Thermal Protection Minimal External Components Available in QFN-28 (4mmx5mm) Package APPLICATIONS      IEEE 802.3af-Compliant Devices Security Camera VoIP Phones WLAN Access Points IoT Devices All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.

Refer to “VCC sinking current” rating and “VCC Power Supply Setting” section. 5) When VDD to Adapter-ground voltage is high, AUX-VDD voltage may exceed -6.5V if the divider resistor is not appropriate, in this condition VDD will clamp the -6.5V voltage on AUX pin, but the current should be limited by external resistor. 6) The maximum allowable power dissipation is a function of the maximum junction temperature TJ (MAX), the junction-toambient thermal resistance θJA, and the ambient temperature TA. The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation produces an excessive die temperature, causing the regulator to go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 7) The device is not guaranteed to function outside of its operating conditions. 8) Measured on JESD51-7, 4-layer PCB.
