NXQ1TXA5 Description
The NXQ1TXA5 is a controller/driver IC for a 5 V Qi-certified/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 NXQ1TXA5 uses dedicated analog ping circuitry to detect devices, according to the Qi standard, achieving extremely low standby power consumption.
