Auto Wireless Charger Transmitter
NU8040Q
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, lowEMI 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.
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.
