Beschreibung

The NXQ1TXA1 is a state of the art digital control controller for Qi-standard conforming wireless charger base stations. The controller supports type A1 or A10 single coil base stations.

The NXQ1TXA1 offers wireless power transfer, WPC 1.1 - Qi low-powerstandard-compliant communication and safety functions including Foreign Object Detection (FOD), temperature monitoring and more. The controller supports the conventional WPC pinging mode during standby to identify potential receivers. The controller can also work with the trigger function of the NXP NTAG I2C product. This feature enables wake up from a phone its NFC field while having zero power consumption of the charger during standby. The controller also offers a flexible User Interface (UI) withup to two LEDs and one buzzer for feedback and control.

Depending on the required charging pad area, coil configurations such as A1 (single coil with magnet) and A10 (single coil without magnet) are supported.
