Wireless charging module:
15W-TXP9242 transmitter module consists of the 50mm Tx A2 coil (see later description) with an integrated electronics PCB. Already passed WPC1.2.2 QI certification .
The 15W-TXP9242 transmitter module offers a Coil-to-coil charging distance up to 4-6mm(+/- 1mm).
The 15W-TXP9242 transmitter module accepts QC3.0 Qualcomm quick-charge Adapters which provides 12V1.6A 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.
