NX1WP10 - A4WP compliant high frequency wireless charging receiver front end - Wireless power receivers - 電源管理IC - 恩智浦, LLC
The NX1WP10 is an A4WP (Alliance for Wireless Power) compliant wireless power receiverfront end. It contains a high-voltage, highly efficient active rectifier, integratedLDOs, a DC-to-DC converter, a multi-channel 12-bit ADC, four GPIOs and a Fast-ModeI2C-bus interface. The integrated rectifier supports voltages of up to 20V and is protected by an integrated automatic clamping function and an automaticdetuning function. The DC-to-DC regulator delivers an adjustable output voltage between4.2 V and 10 V with a maximum DC current of up to 1.1 A. It is used to charge portabledevices through a PMU or a charging controller. The integrated LDOs are directly linkedto the rectifier output. They are automatically enabled once a sufficient voltage levelat the output of the rectifier is reached. These voltages are used to supply thecorresponding wireless power receiver controller and BT-LE transceiver. The hostmicrocontroller configures the on-chip controller for automatic interrupt-driven systemcontrol.
The microcontroller can measure the rectifier output voltage, current level information,junction temperature and external temperature sensor information with the ADC. Itcontrols the DC-to-DC converter as well as the GPIOs. Key safety functions areimplemented with low power analog comparators. For example, one of the selectable safetyfunctions prevents the junction temperature from exceeding its limits by automaticallydetuning the antenna. The overall system efficiency from the antenna input to theDC-to-DC output reaches 86 %.
