NXP 12V Qi Low Power A6 Transmitter Solution

The NXQ1TXA6 wireless power transmitter controller provides a flexible architecture that supports one, two or three coil configurations. The NXQ1TXA6 automatically detects the presence and number of coils connected and configures itself accordingly. The design implements three NXP NWP2081 half-bridge drivers and NXP low RDSon NX2020N2-channel MOSFETs for high efficiency. The integrated NXP NT3H1201 NTAG I²C solution provides the option of adding exciting features such as automatic Bluetooth pairing, or allowing users to configure their wireless chargers and even automatically launch applications on their NFC-enabled smartphones. The Qi A6 wireless power transmitter is powered by the NXP GreenChip TEA1720 high-efficiency switch mode power supply (SMPS) controller in the power unit, making it a more optimized 12 V wireless charging solution.
