BQ51013BRHLR

The BQ51013BRHLR from Texas Instruments is a single-chip, advanced, flexible, secondary-side device for wireless power transfer in portable applications, capable of providing up to 5 W. This IC handles the receiver (RX) AC-to-DC power conversion and regulation, integrating the digital control required to comply with the Wireless Power Consortium (WPC) Qi v1.2 communication protocol.

Key electrical specifications include an input voltage range of 4V to 10V, with an absolute maximum input voltage of 20V. It operates within a temperature range of 0°C to 125°C. The device offers a peak AC-DC efficiency of 93% and can deliver up to 5W of output power, with a maximum current rating of 1.5A.

Packaged in a 20-VQFN (3.5x4.5 mm) format, the BQ51013BRHLR is designed for surface mount applications. It features a full synchronous rectifier and WPC v1.2 compliant communication control. The IC requires only itself between the Rx coil and the output, simplifying system design. It also includes features like Foreign Object Detection (FOD) enabled communication, highly accurate current sense, dynamic rectifier control, dynamic efficiency scaling, and adaptive communication limits for robust performance.

This device enables a complete contactless power transfer system when paired with a primary-side controller like the BQ50012A. Its integrated solution simplifies the design of wireless power supply systems for various portable electronic devices.
