Product Feature:

The module consists of INJOINIC Power management module and 5W wireless charging module.

The Support for charge side discharge fuction , USB output and wireless charging output at same time, whether input power is connencted or not. In order to have better efficiency, the wireless charging part adopts 1pc NU1007 integrated coil driver and 1pc built-in MOS full-bridge driver IC. Also resonant capacitors- Murate NPO 104 helps high-efficiceny working status.

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

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.
