NXQ1TXH5 Datasheet by NXP USA Inc.
1. General description
The NXQ1TXH5 is a controller and driver IC for a 5 V Qi-certified/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 NXQ1TXH5 uses a dedicated analog ping circuitry to detect devices. With the analog
pin circuitry, an extremely low standby (wait state) power consumption is achieved. When
a Qi-compliant receiver is placed, the NXQ1TXH5 starts to communicate with it. After the
receiver is recognized, it safely initiates wireless power transfer from the transmitter to the
receiver, while monitoring for fault conditions such as overheating or interference from
metal objects. 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. The device supports Foreign Object Detection (FOD).
LED outputs and a buzzer output are available for the user interface. The LED outputs
feature a number of blinking modes. Static Power Reduction (SPR) allows multiple
NXQ1TXH5-based transmitters to operate from a single USB power supply by limiting
power consumption per device.
The NXQ1TXH5 is available in a 5 mm 5 mm, 32-pin HVQFN package.

NXP Semiconductors NXQ1TXH5
One-chip 5 V Qi wireless transmitter
8. Functional description
The NXQ1TXH5 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 NXQ1TXH5. It is operational when a 5 V supply is
connected and pin STBY is LOW. The NXQ1TXH5 starts checking for a device on the
transmitter base station. When a receiver is detected, power transfer is initiated for the
detected receiver.
The power transfer can be monitored via the LEDs and BUZZER outputs.
Additional inputs are provided for configuring the NXQ1TXH5:
•LED mode selection
•Configuring FOD according to the application design and coil/capacitor selection
•Setting the SPR level
•Enabling/disabling SPL
8.1 NXQ1TXH5 operating states
The NXQ1TXH5 supports a number of operating states:
•Power-on state:
The NXQ1TXH5 generates a power-on LED blinking sequence after which it is
operational (standby = low).
•Standby state:
The device is inactive in standby state. The NXQ1TXH5 is in standby state when pin
STBY is HIGH. STBY must be connected to ground in standalone applications.
•Wait state (analog and digital ping):
The NXQ1TXH5 performs extremely low-power device detection using analog
circuitry in analog ping mode. The NXQ1TXH5 performs standard device detection
using the DSP in digital ping mode.
•ID and config state:
The NXQ1TXH5 communicates with and begins to supply power to a Qi-compliant
receiver.
•Power transfer state:
The NXQ1TXH5 charges the Qi-compliant receiver in power transfer state.
•Charged state:
The NXQ1TXH5 switches to charged state when it receives a ‘charge complete’
message from the receiver.
•Fault state:
The NXQ1TXH5 switches to a fault state when:
– A receiver error is reported
–A foreign object is detected between receiver and the transmitter
–A receiver/transmitter overtemperature condition occurs

10. Thermal characteristics
11. Characteristics
[1] 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.

NXP Semiconductors NXQ1TXH5
One-chip 5 V Qi wireless transmitter
12. Application information
12.1 Crystal oscillator
The NXQ1TXH5 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 NXQ1TXH5). Do not connect the crystal to the NXQ1TXH5 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 NXQ1TXH5 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 NXQ1TXH5 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. To have
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 NXQ1TXH5 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 tune the FOD resistors and to check DSP operation. To connect the interface
wires, the NXQ1TXH5 I2C 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 the I2C test-pad connections. Do not connect
pull-up resistors to VDDP for the I2C interface pins. For more advanced debug options for
NXP Semiconductors, pins 1, 2, and 32 require the same test options.

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

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

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.
