NU8040Q: Integrated Power Stage for High-Integration and

High-Efficiency Medium-Power Wireless Power Transmitter

1 Features

3 Descriptions

NU8040Q 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.

•

Wide Input Voltage: 4V to 21V

Integrated 9A rating High-Efficiency

Full- Bridge FETs

Integrated FET Driver Optimized for

Low EMI

•

Integrated 5V DC/DC for IC power

supply

Integrated 3.3V (2.5V configurable)

LDO to Bias External Circuit and

Provide Reference Voltage

High-Accuracy, Lossless Current

Measurement for FOD and In-Band

Communication

Integrated Lossless Q Factor Detection

Integrated Low-Error-Rate Digital

Demodulation

•

NU8040Q is qualified for automotive

applications. For higher power cases like

50W, NU8040Q can be used in parallel to

handle it with good thermal dissipation

methods.

•

Input UVLO and OVP

Over-Current Protection

Thermal Shutdown

I²C Interface

AEC-Q100 Grade 2 qualified

4mm4mm QFN Package

The IC also includes protection functions

such as input under-voltage lockout, over-

voltage

protection,

over

current

protection, and thermal shutdown. These

provisions further enhance the reliability

of the total system solution.

•

Wireless Power Transmitter

Compliant with WPC V1.2.4 Extended

Power Profile(EPP)

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.
