NXQ1TXH5: One-chip 5 V Qi wireless transmitter
The NXQ1TXH5 is a fully integrated one-chip controller and driver IC enabling the design
of a 5 V Qi-certified low-power wireless charger. It includes a 5 V full-bridge power
stage, as defined in the Wireless Power Consortium (WPC) low power Qi configurations A5,
A11, A12 and A16. The device is optimized for minimum external component count, enabling
a very low cost application and a simple PCB design.
The NXQ1TXH5 uses dedicated analog ping circuitry to detect devices, according to the Qi
standard, achieving an extremely low standby power consumption of 10 mW. The NXQ1TXH5
takes care of a reliable ASK communication and controls the wireless power transfer from
the transmitter to the receiver, while monitoring for fault conditions such as
overheating or interference by metal objects. The device is optimized to operate from a
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), and operates according to the WPC Qi low power V1.2
specifications.
LED and buzzer outputs are available for the user interface. For the LED outputs a wide range
of blinking modes can be selected in the application. 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 comes in a size optimized low cost 5 mm × 5 mm, 32-pin HVQFN package.

The NXQ1TXH5 comes only as the NXQ1TXH5/101 version. NXP® also provides the
NXQ1TXA5/505 version that is pin-compatible with earlier NXQ1TXA5 devices. The
latest NXQ1TXH5/101 devices are not pin-compatible with earlier devices of NXP. The
NXQ1TXH5/101 has dual channel ASK for improved charging robustness at very low
charging powers or noisy environments. It also provides superior support for low
cost Qi receivers with noisy or weak ASK modulation. This makes the NXQ1TXH5/101
ideally suitable for general purpose Qi charger applications to support a very wide
range of receiver devices, coping with any type of modulation anomalies.
The NXQ1TXH5/101 provides the following updates:
- Dual channel ASK for superior charging robustness
- Very wide range of Qi receivers supported
- Compliant to the latest WPC Qi Low Power V1.2 specifications
- Extended range of pre-defined LED blinking modes, selectable in the
application
- Shorter charging startup time for receiver. Faster PID loop
- Extended Smart Power Reduction (SPR) range (500 – 1500 mA in 10 mA steps)
- Extended FOD range for better placement freedom
- Easy FOD tuning for Qi certification
