The NXQ1TXA5 is a controller/driver IC for a 5 V Qi-compliant wireless charger. It offers a fully integrated solution that uses a 5 V full-bridge power stage to drive a power transmitter, as defined in the 5 V A5, A11 and A12 Qi standards.
The NXQ1TXA5 has dedicated analog ping circuitry to detect available devices, according to the Wireless Power Consortium (WPC) Qi standard, which achieves extremely low standby power consumption. If a Qi-compliant receiver is detected, it will attempt to communicate with it. If the receiver is recognized, it will safely initiate wireless power transfer from the transmitter to the receiver, while monitoring for any fault conditions like interfering metal objects or overheat conditions. The device is optimized to operate from a USB power supply and can handle also limited supply power conditions by automatic adjustment of the output power, called Smart Power Limiting (SPL).
For the user interface LED outputs are available with several blinking modes as well as a buzzer output. Additional features like Static Power Reduction (SPR) allow multiple NXQ1TXA5 based transmitters to operate from a single USB power supply.
The NXQ1TXA5 is available in a 5 x 5 mm, 32 pin HVQFN package with 0.5 mm pitch.
