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. The integrated LDOs are directly linked to the rectifier output.
They are automatically enabled once a sufficient voltage level at the output of the rectifier
is reached. These voltages are used to supply the corresponding wireless power receiver
controller and BT-LE transceiver. The host microcontroller configures the on-chip
controller for automatic interrupt-driven system control.
The microcontroller can measure the rectifier output voltage, current level information,
junction temperature and external temperature sensor information with the ADC. It
controls the DC-to-DC converter as well as the GPIOs. Key safety functions are
implemented with low power analog comparators. For example, one of the selectable
safety functions prevents the junction temperature from exceeding its limits by
automatically detuning the antenna. The overall system efficiency from the antenna input
to the DC-to-DC output reaches 86 %.
2. Features and benefits
