Wirless Charger PCBA With IWatch

1. Product Definition

APPLE WATCH-TX1806 transmitter module consists of the 20mm Tx coil (see later description) with an integrated electronics PCB.

For the APPLE WATCH-TX1806 transmitter module offers a Coil-to- Apple watch surface charging distance 1.5mm(+/- 0.2mm).

For the APPLE WATCH-TX1806 transmitter module accepts 5V02.A power input , 0%-100% full charged of apple watch within 3hours .

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.
