1. Wireless charging module:

QI-TX1806 transmitter module consists of the 50mm Tx coil (see later description) with an integrated electronics PCB. Already passed WPC1.2.4 QI certification .

The QI-TX1806 transmitter module offers a Coil-to-coil charging distance up to 8mm(+/- 1mm).

The QI-TX1806 transmitter module accepts QC2.0/3.0 Qualcomm quick-charge Adapters which provides 5V2A or 9V1.67 input on demand.

Thermal management system is designed to stop power transfer when the sense temperature is exceeding safety threshold while auto-resume mechanism would rescan the device when the temperature cool down to safety level.
