BQ51013BYFPR

The bq51013BYFPR is TI’s Qi-compliant wireless power receiver IC. It receives energy from a compatible transmitter coil, rectifies it, and regulates it to power the system or charge a battery. The device integrates the rectifier, a switching regulator/power-management block, and protection features, enabling high efficiency and safe operation with minimal external parts. Key capabilities include power-path management, undervoltage/overcurrent/overtemperature protection, and coil-to-device communication per the Qi standard. It’s intended for wireless charging applications in consumer electronics such as smartphones, wearables, and other battery-powered devices. The BYFPR suffix denotes a specific TI package/packaging variant. For exact electrical characteristics, layout guidelines, and packaging details, consult the BQ51013B datasheet and TI packaging information.
