GPMQ8102A is a single-chip, advanced, flexible, secondary-side device for wireless power transfer in portable applications up to 4W with high integration, high efficiency, and low power consumption advantages. GPMQ8102A receives the power that uses the near field electromagnetic induction principle; the power transfer is through coupling between the transmitter coil (primary) and receiver coil (secondary). Global feedback is established from the secondary to the primary to control the power transfer process using the Qi V1.3 protocol. GPMQ8102A is integrated a low resistance synchronous rectifier (AC to DC), low-dropout regulator (LDO), digital control, and accurate voltage and current loops to improve the high efficiency and decrease the power dissipation. GPMQ8102A is also integrated a digital controller that complies with the WPC V1.3 standard and can calculate the amount of power received by the mobile device; the controller then communicates this information to the transmitter that allows the transmitter to determine if a foreign object is present within the magnetic interface and introduces a higher level of safety within magnetic field. This foreign object detection (FOD) is part of requirement under the WPV v1.3 specification. GPMQ8102A output stage is LDO and the output voltage is adjusted dynamically according to the output current to achieve the best transient and efficiency.
