Protect function:
Data transfer code is the core technology of wireless charging system .
Wireless charging is conform to the WPC material identification number, for metal, magnetic material, and does not meet the QI standard products into the detection and identification to determine whether the output power to ensure the safety of the product.
The function instructions:
4.1 RX coil surface placed in QI emitter, after 2 seconds to execute QI agreement to the code and then normal output voltage and current, such as the code fails, no output.
4.2 when receiving module return (magnetic isolation one-sided when placed on QI TX) placed, for disk from the fluctuation of code, normal should be to code without output failure.(e.g., still can normal to code that every disk damaged or poor quality of disk magnetic flux leakage).
