Product Overview

High efficiency wireless power receiver and battery charger with integrated Li-Ion/LiPol battery charge controller. It provides efficient AC to DC power conversion and integrates the digital controller required to comply with Qi v1.2 communication protocol and provides all necessary control algorithms needed for efficient and safe Li-Ion and LiPol battery charging. The device integrates a low impedance synchronous rectifier, low-dropout regulator (LDO), digital control, charger controller and accurate voltage and current loops in a single package. The entire power stage (rectifier and LDO) use low resistance N-MOSFETs (100mohm typical Rdson) to ensure high efficiency and low power dissipation. Typically used in battery packs, cell phones and smart phones, Headsets, portable media players and handheld devices.
  • Robust architecture
  • 4.2V output voltage
  • 93% peak AC-DC charging efficiency
  • Thermal shutdown and overcurrent protection
  • Temperature monitoring and fault detection
  • Power stage output tracks rectifier and battery voltage to ensure maximum efficiency
