The BQ51013C-Q1 device is a single-chip, advanced, flexible, secondary-side device for wireless power transfer in portable applications capable of providing up to 5W. The BQ51013C-Q1 devices provide the receiver (RX) AC-to-DC power conversion and regulation while integrating the digital control required to comply with the Wireless Power Consortium (WPC) Qi v2.0 communication protocol. Together with the BQ500212A primary-side controller (or other Qi transmitter), the BQ51013C-Q1 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 transfer process using the Qi v2.0 protocol.
The BQ51013C-Q1 integrates a low-resistance synchronous rectifier, low-dropout regulator (LDO), digital control, and accurate voltage and current loops to ensure high efficiency and low power dissipation.
The BQ51013C-Q1 also includes a digital controller that calculates the amount of power received by the mobile device within the limits set by the WPC v2.0 standard. The controller then communicates this information to the transmitter (TX) to allow the TX 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) method is part of the requirements under the WPC v2.0 specification.
