Charging your phone by just placing your phone on a charging surface? Without the need of plugging in a wire? That sounds exciting and it actually is, giving also the convenience of charging on-the-move when charging spots are available in public places like airports or bars.

The NXQ1TXH5 our latest one-chip low power Qi transmitter device that enables an ultra-low cost wireless charging transmitter, and dramatically reducing application cost while still providing Qi certified performance.  It meets the latest Wireless Power Consortium (WPC) V1.2 standard.

The NXQ1TXH5 is provided in an exciting form-factor with a backlight module on which Qi enabled phones can be charged. The demonstration shows as well the extremely low component count, which is interesting for professionals to understand, and at the same time showing a real-life eye-catching form-factor that draws non-technically skilled person’s attention. The demonstration challenges people to actually charge their phone and experience charging without wires.

The table module is provided with a table-fan in which there is a Qi power receiver built-in. It can be used as a standby-demo to further draw attention to the demo, even when no phone is placed, and it avoids phones getting lost when there is no expert attending the demo.

NXP provides reference designs in different formfactors depending on application requirements, and the low component count makes PCB design extremely simple.
