NXQ1TXL5: low-cost one-chip 5 V Qi wireless transmitter
The
NXQ1TXL5 is a low cost drop-in replacement for the NXQ1TXH5 one-chip low power Qi charger
transmitter device. The NXQ1TXL5 is a fully integrated one-chip controller and driver IC
enabling the design of a 5 V Qi-compliant 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 NXQ1TXL5 has all benefits and the same high integration level of the NXQ1TXH5 device, but it comes with less configuration options and does not support Foreign Object Detection (FOD). The NXQ1TXL5 application becomes extremely simple, enabling a true plug & play experience for the design of a low power Qi-compliant wireless charger for applications that do not require to meet full Qi certification requirements. The fixed configuration enables even further reducing the component count and allowing an even simpler PCB layout, even though it can also be used to drop into an existing NXQ1TXH5 PCB layout, omitting the external configuration resistors.
The NXQ1TXL5 uses dedicated analog ping circuitry to detect devices, according to the Qi standard, achieving an extremely low standby power consumption of 10 mW. The NXQ1TXL5 takes care of a reliable ASK communication and controls the wireless power transfer from the transmitter to the receiver. LED outputs are available for the user interface and the LED blinking modes is fixed.
The NXQ1TXL5 comes in a size optimized low cost 5 mm × 5 mm, 32-pin HVQFN package.

Whereas the NXQ1TXH5 meets all requirements for the design of a WPC Qi low power V1.2 certified wireless charger, the NXQ1TXL5 has reduced functionality for dedicated wireless charging applications that do not require Qi certification, but still need to operate with Qi compliant receivers. The functionality of the NXQ1TXL5 is limited as follows:
- No buzzer output available
- No NTC input available
- Foreign Object Detection is not supported
- Single LED blinking mode indicating charging modes (standby, charging, charged) and error modes
- Power consumption cannot be limited (no SPR functionality); fully Qi-compliant power control
- Maximum power delivery at voltage levels down to 4 volt, without smart power limiting (SPL) at dropping supply voltages
The NXQ1TXL5 will support following functions in the same way as the NXQ1TXH5:
- Dual channel ASK for superior charging robustness
- Very wide range of Qi receivers supported
- Short charging startup time for receiver. Faster PID loop
- Very low EMI
- Very low power device detection circuitry
- Over-temperature, over-voltage, over-power protections
- Qi-compliant response to receiver error messages
