TIBQ51013B
Overview
The BQ51013B is a highly integrated, advanced receiver IC for wireless power transfer, compliant with the WPC v1.2 Qi standard. It operates as an AC-to-DC power converter, integrating a full synchronous rectifier, low-dropout regulator, and digital control logic to manage the wireless power communication protocol. This device is designed to provide a regulated 5V output at up to 1.5A from a wireless receiver coil.
Why Choose This Part
The IC provides 93 percent peak efficiency and integrates all necessary functions between the receiver coil and the output, minimizing external component count. It features dynamic rectifier control for improved load transient response and Foreign Object Detection (FOD) for safety. The wide 4V to 10V supply range and 20V input tolerance protect the system during power spikes or alignment shifts.
Applications
Key Specifications
Getting Started
Designers should begin with the BQ51013BEVM-764 evaluation module to test coil alignment and thermal performance. Ensure the resonant circuit components are tuned precisely to the Qi frequency specification using high-Q COG/NP0 capacitors. Refer to Texas Instruments' web-based tools for calculating the Foreign Object Detection (FOD) calibration parameters required for WPC compliance.
