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
I
2
C-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 %.

Definitions
Draft —
The document is a draft version only. The content is still under
internal review and subject to formal approval, which may result in
modifications or additions. NXP Semiconductors does not give any
representations or warranties as to the accuracy or completeness of
information included herein and shall have no liability for the consequences of
use of such information.
Short data sheet —
A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Product specification —
The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.
Suitability for use —
NXP Semiconductors products are not designed,
authorized or warranted to be suitable for use in life support, life-critical or
safety-critical systems or equipment, nor in applications where failure or
malfunction of an NXP Semiconductors product can reasonably be expected
to result in personal injury, death or severe property or environmental
damage. NXP Semiconductors and its suppliers accept no liability for
inclusion and/or use of NXP Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at the customer’s own
risk.
Applications —
Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
Limiting values —
Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those given in
the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
