The bq51013B device is a single-chip, advanced, flexible, secondary-side device forwireless power transfer in portable applications capable of providing up to 5 W. The bq51013Bdevices provide the receiver (RX) AC-to-DC power conversion and regulation while integrating thedigital control required to comply with the Wireless Power Consortium (WPC) Qi v1.2 communicationprotocol. Together with the bq50012A primary-side controller (or other Qi transmitter), thebq51013B enables a complete contactless power transfer system for a wireless power supply solution.Global feedback is established from the secondary to the primary to control the power transferprocess using the Qi v1.2 protocol.

The bq51013B integrates a low-resistance synchronous rectifier, low-dropout regulator(LDO), digital control, and accurate voltage and current loops to ensure high efficiency and lowpower dissipation.

The bq51013B also includes a digital controller that calculates the amount of powerreceived by the mobile device within the limits set by the WPC v1.2 standard. The controller thencommunicates this information to the transmitter (TX) to allow the TX to determine if a foreignobject is present within the magnetic interface and introduces a higher level of safety withinmagnetic field. This Foreign Object Detection (FOD) method is part of the requirements under theWPC v1.2 specification.
