NXQ1TXL5
Low-cost one-chip 5 V Qi compliant transmitter
Rev. 1 — 8 April 2016
Product short data sheet
1. General description
The NXQ1TXL5 is a controller and driver IC for a low-cost 5 V Qi-compliant low-power
wireless charger. It offers a fully integrated solution that includes a 5 V full-bridge power
stage, as defined in Wireless Power Consortium (WPC) 5 V Qi standards A5, A11, A12
and A16.
The NXQ1TXL5 uses a dedicated analog ping circuitry to detect devices. With this analog
ping circuitry, an extremely low standby (wait state) power consumption is achieved.
When a Qi-compliant receiver is placed, the NXQ1TXL5 starts to communicate with it.
After the receiver is recognized, it safely initiates wireless power transfer from the
transmitter to the receiver. The device is optimized to operate from a 5 V USB power
supply and uses Smart Power Limiting (SPL) to adjust the output power automatically to
compensate for power-limited supplies. This low-cost version of the fully integrated NXP
Qi-compliant wireless power transmitted does not support Foreign Object Detection
(FOD).
To indicate the charging status or standby status, the NXQ1TXL5 has two LED outputs for
the user interface.
The NXQ1TXL5 is available in a 5 mm 5 mm, 32-pin HVQFN package.

For enhanced thermal and electrical performance the exposed die-pad (33), the GNDP and GNDD
pins must be directly connected to the top layer board ground (GNDD). The exposed die-pad must
also be connected to bottom layer board ground with plated-through vias (see Section 12.4).

Low-cost one-chip 5 V Qi compliant transmitter
8. Functional description
The NXQ1TXL5 is a fully integrated 5 V wireless charger with an internal full-bridge power
stage. It efficiently integrates all the functions required to control the power transfer with a
Qi-compliant receiver. It can deliver up to 8 W continuous power into the Qi-compliant
type A5, A11, A12 or A16 transmitter coil.
Figure 1 shows a block diagram of the NXQ1TXL5. It is operational when a 5 V supply is
connected and pin STBY is LOW. The NXQ1TXL5 starts checking for a device on the
transmitter base station. When a receiver is detected, power transfer is initiated for the
detected receiver.
8.1 NXQ1TXL5 operating states
The NXQ1TXL5 supports a number of operating states:
• Power-on state:
The NXQ1TXL5 generates a power-on LED blinking sequence after which it is
operational.
• Wait state (analog and digital ping):
The NXQ1TXL5 performs extremely low-power device detection using analog circuitry
in analog ping mode. The NXQ1TXL5 performs standard device detection using the
DSP in digital ping mode.
• ID and config state:
The NXQ1TXL5 communicates with and begins to supply power to a Qi-compliant
receiver.
• Power transfer state:
The NXQ1TXL5 charges the Qi-compliant receiver in power transfer state.
• Charged state:
The NXQ1TXL5 switches to charged state when it receives a ‘charge complete’
message from the receiver.
• Fault state:
The NXQ1TXL5 switches to a fault state when:
–
A receiver error is reported
– A receiver/transmitter overtemperature condition occurs

The maximum DC VDDP input voltage is 5.25 V. However, at the maximum load, spikes can occur due to high dI/dt. With the proper
decoupling circuitry and snubbers at the outputs, these spikes must never exceed 7 V (see Section 12.2 and Section 12.3).
[2]
The current consumption depends on the load impedance of the LC tank connected to the output stage at 175 kHz.
Assumed typical value: L = 6.3 F, 60 m and C = 384 nF.

Low-cost one-chip 5 V Qi compliant transmitter
12. Application information
12.1 Crystal oscillator
The NXQ1TXL5 uses an external low-cost 32.768 kHz crystal, with a 1 % accuracy. The
crystal should support a load capacitance of 12 pF (the load capacitance is embedded in
the NXQ1TXL5). Do not connect the crystal to the NXQ1TXL5 using vias, but directly on
the top layer of the PCB. If possible, shield the crystal by connecting the casing to ground.
The crystal is connected to the oscillator input pin (XTAL_IN) via a 2.2 pF series capacitor.
12.2 Supply decoupling
Effective supply decoupling is required. The decoupling capacitors must to be chosen
such that the effective capacitance is at least 10 F at a DC bias voltage of 5.5 V. The
frequency must be 205 kHz for each supply pin. X5R capacitors of 22 F normally fulfill
this requirement. To prevent spikes that are too high on the VDDP pins and to improve HF
behavior and reduce EMI, use smaller (10 nF) high-quality capacitors. These capacitors
must be mounted as close as possible to the VDDP pins of the NXQ1TXL5 in parallel with
the 22 F capacitors (see Figure 4).
12.3 Snubber network
Snubber RC networks are connected to outputs OUT1 and OUT2. Each snubber network
consists of a 6.8 nF capacitor in series with a 1 resistor to ground (see Figure 4). The
snubber network must be connected as close as possible to the NXQ1TXL5 OUT1 and
OUT2 pins.
12.4 Exposed die-pad ground and thermal connection
For optimal thermal and electrical performance, the device bottom exposed VSS pin
(pin 33) MUST be soldered to a PCB solder land under the exposed die-pad. For good
electrical contact and thermal flow from the device to the bottom copper layer, the PCB
solder pad under the device must be connected with plated-through vias to the copper
bottom layer of the PCB. In this way, the PCB bottom copper layer can provide heat
sinking for the device dissipation.
In the NXQ1TXL5 application note examples are provided for recommended layouts with
good thermal and electrical performance.
12.5 Support interface
For NXP Semiconductors support purposes, connecting interface wires must be made
possible to check DSP operation. To connect the interface wires, the NXQ1TXL5 the test
interface pins (pins 3 and 4) must be made available on the PCB layout as exposed
test-pads with minimum 2 mm2 solder area. A test pad for ground connection must also be
placed close to these test-pad connections. Do not connect pull-up resistors to VDDP for
the test interface pins.

Product short 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

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

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
the quality and reliability of the device.
