NX1WP10 Description
The NX1WP10 is an A4WP (Alliance for Wireless Power) pliant wireless power receiver front end. It contains a high-voltage, highly efficient active rectifier, integrated LDOs, a DC-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 detuning...
