The NXQ1TXH5 from NXP is a one-chip 5V Qi wireless transmitter. It is a fully integrated, single-chip controller and driver IC that enables engineers design a WPC 1.2 Qi-compliant low-power wireless charger with Foreign Object Detection (FOD). This transmitter includes a 5V full-bridge power stage and efficiently integrates all the functions required to control the power transfer with a Qi-compliant receiver. It delivers up to 8 Watts of continuous power into a Qi-compliant type A5, A11, A12, or A16 transmitter coil, and requires minimal external components, reducing application costs and enabling a simple PCB design for wireless power chargers and transmitters. This transmitter uses dedicated analog ping circuitry to detect devices, achieving an extremely low standby power consumption of 10 mW. This device is optimized to operate from a 5 Volt USB power supply and uses Smart Power Limiting (SPL) to adjust the output power automatically to compensate for power-limited supplies. It is available in a 32-pin, 5 × 5 mm HVQFN package with low electromagnetic interference (EMI) radiation and is ideal for smartwatches, wearable devices and smartphones.
