Generalplus GPMQ8102A 1. GENERAL DESCRIPTION 2. FEATURES GPMQ8102A is a single-chip, advanced, flexible e Integrated Wireless Power Supply Receiver secondary-side device for wireless power transfer in portable Solution applications capable of providing up to 4 W. It has high integration, High Efficiency Full Synchronous Rectifie high efficiency, low power consumption Output Voltage Conditioning GPMQ8102A receiver the power that uses the near field WPC Qi V1.2.2 Compliant communication electramagnetic induction principle, the power transfer is through Contro coupling between the transmitter coil (primary) and receiver coil Single IC Required Between RX Coil and Output (sccondary), Global fccdback is established from the sccondary O WPC Qi V1.2.2 FOD Function to the primary to control the power transfer process using the Qi Support I"C Internal Register Configuration V1. 2.2 protocol Output Current -VRECT GPMQ8102A integrated a low resistance synchronous Outout Current -lOUT rectifier(AC to DC), low-dropout regulator (LDo), digital control ● Dynamic Rectifier VRECT and accurate voltage and current loops to improve the high Improve the load Transient Response efficiency and decrease the power dissipation Optimize the dynamic efficiency for full load GP MQ8102A also integrated a digital controller that comply output ith the wpc v1.2.2 standard. it can calculate the amount of Rectifier Overvoltage Clamp(VOVP=15V) power received by the mobile device, the controller then Support 20 V Maximum Input communicates this information to the transmitter to allow the e Over Temperature Over Voltage and over current Protection transmitter to determine if a foreign object is present within the Open Drain LED Output Indication magnetic interface and introduces a higher level of safety within Multifunction NTc and Temperature Monitoring, Charge magnetic field. This foreign object detection(FOD)method is part Complete and Fault Host Control of requirement under the WPV V1.2.2 specification e Compatible with Adapter and USB Input Application GPMQ8102A Output stage is LDO, the output voltage is QFN 4mm'4mm 24Pin Packaeg adjusted dynamically according to the output current to achieve the best transient and eff GPMQ8102A supports Ic internal register configuration The output voltage and current can be flexibly configured according to the application case o Gcncralplus Technology Inc 3 APR.05,2017 Proprietary & Confidential Version: 1.0 Generalplus GPMQ8102A 3.
