NU8015Q: Integrated Power Stage for High-Integration and

High-Efficiency Medium-Power Wireless Power Transmitter

1 Features

3 Descriptions

•

Wide Input Voltage: 4V to 21V

NU8015Q is a family of highly integrated

full-bridge power stage IC optimized for

wireless power transmitter solutions. The

device integrates all critical functions,

such as high-efficiency power FETs, low-

EMI FET drivers, bootstrap circuit, 5V

integrated DC/DC power supply, 3.3V

(2.5V configurable) LDO and lossless

current measurement. The proprietary

current-measurement circuit provides the

accurate current reading used for the FOD

(Foreign Object Detection) power

measurement, in-band communication, Q

factor detection, and digital demodulation.

protection, and thermal shutdown. These

provisions further enhance the reliability

of the total system solution.

I2C interface is used for communication

with the controller and can easily be

extended to multi-coil solutions. The

device is housed in a thermally enhanced

4mm×4mm QFN package.
