This mode PCBA has good compatibility with 5W wireless charging mobile phone and support Ti, IDT, PANASONIC, and others Qi standard receiver.

1. Wireless charging module:

This mode PCBA has good compatibility with 5W wireless charging mobile phone and support Ti, IDT, PANASONIC, and others Qi standard receiver.

The PCBA design engineer use 2pcs of TI 97374 IC to drive wireless charging working .the wireless charging efficiency achieve to be 90% .

Power input 5V1.5A power control IC driver MOS transistors (Drive circuit),MOS push-pull resonant capacitance and inductance, issued 50V voltage 105-189K shock power,Communication module detects the received feedback information to the MCU,Feedback information processing modulation frequency is 500-1000Hz,At the same time electrical detection module will send back to the transmit power MCU,MCU based on feedback to adjust the transmit frequency,The circuit control within a certain range. Wherein the main operating frequency is 48MHz.LED have blue and green color, the power will turn every 0.5S bright look.Standby completely destroyed, charging blue lights up, full of green light.when an error occurs, double light flashing.

2. Transmitter Module Unit Summary

1. The PCBA have a really very smaller size

2. MOS driver use TI 97374 chip high performance

3. Certificates can pass CE FCC RohS

4. Working temperature under 35 ℃ ， working time More than 20000 hours .
