NX1A4WP: A4WP compliant high frequency wireless charging receiver front end
The NX1A4WP is an A4WP (Alliance for Wireless Power) compliant wireless power receiver front end. It contains a high-voltage, highly efficient rectifier, integrated LDOs, a D1C-to-DC converter, a multi-channel 12-bit ADC, four GPIOs and a Fast-Mode I²C-bus interface. The integrated rectifier supports voltages of up to 20 V and is protected by an integrated automatic clamping function and an automatic over-power protection function. The DC-to-DC regulator delivers a nominal voltage of 5 V. The host microcontroller configures the on-chip controller for automatic interrupt-driven system control. The controller reads the rectifier output voltage, current level information, junction temperature and external temperature sensor information from the ADC. It controls the DC-to-DC converter as well as the GPIOs.
