NXQ1TXL5 Overview
The NXQ1TXL5 is a controller and driver IC for a low-cost 5 V Qi-pliant low-power wireless charger. It offers a fully integrated solution that includes a 5 V full-bridge power stage, as defined in Wireless Power Consortium (WPC) 5 V Qi standards A5, A11, A12 and A16. The NXQ1TXL5 uses a dedicated analog ping circuitry to detect devices.
