NX1WP10 - A4WP compliant high frequency wireless charging receiver front end

Description

The NX1WP10 is an A4WP (Alliance for Wireless Power) compliant 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.

Features

  • 25 V tolerant antenna input pins.
  • Automatic over-voltage protection of the antenna inputs.
  • 6.78 MHz compatible integrated rectifier.
  • High efficiency with an active rectifier and a DC-to-DC converter.
  • AC input to DC-to-DC output efficiency exceeding 86 % at 6 to 9 W output.
  • Integrated LDOs (1.8 V and 3.3 V up to 50 mA) with auto enable and discharge path.
  • Integrated DC-to-DC buck regulator with 4.2 V to 10 V, 1.1 A output.
  • Multi-channel 12-bit ADC subsyste.

NX1WP10 A4WP compliant high frequency wireless charging receiver front end Rev. 1 — 1 October 2015 Objective short data sheet 1. General description The NX1WP10 is an A4WP (Alliance for Wireless Power) compliant 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 function. The DC-to-DC regulator delivers an adjustable output voltage between 4.2 V and 10 V with a maximum DC current of up to 1.1 A. It is used to charge portable devices through a PMU or a charging controller.
