Product Overview

The BQ51051BRHLT is a high-efficiency, Qi-compliant Wireless Power Receiver with an integrated Li-Ion/LiPol battery charge controller. The device provides efficient AC to DC power conversion, integrates the digital controller required to comply with Qi v1.1 communication protocol and provides all necessary control algorithms needed for efficient and safe Li-Ion and LiPol battery charging. The AC signal from the receiver coil is then rectified and conditioned to apply power directly to the battery. Global feedback is established from the receiver to the transmitter to stabilize the power transfer process. This feedback is established by using the Qi v1.1 communication protocol. The bq5105xB devices integrate a low-impedance synchronous rectifier, low-dropout regulator (LDO), digital control, charger controller and accurate voltage and current loops. Power stage output tracks rectifier and battery voltage to ensure maximum efficiency across the full charge cycle.
  • Single-stage wireless power receiver and Li-Ion/Li-Pol battery charger
  • 4.20V, 4.35V and 4.40V Output voltage options
  • Supports a charging current up to 1.5A
  • 93% Peak AC to DC charging efficiency
  • Robust architecture - 20V Maximum input voltage tolerance, with input overvoltage protection
  • Thermal shutdown and overcurrent protection
