Excellent Service Team Performance Package for Transmitter and Receiver Main Chips Transmitter Chip α6 QFN 44 8 X 8 Receiver Chip β3H QFN 16 4 X 4 Excellent Service Team

Excellent Service Team Operation How Tx & Rx code Transmit Adjustment of coil displacement Variety power transmit FOD Protection Excellent Service Team

How Tx & Rx code Transmit Distinguish un-available RX device by FDT code Magnetic Shield Receiver Board RX Coil ID signal is encoded by B3H chip. Detection Close code Initiation code ID need to be verified by A6 chip within 3mS. Charging energy Feedback Transmitter Board TX Coil Magnetic Shield Excellent Service Team

Excellent Service Team Adjustment of Coil Displacement Adjustment TX power for coil displacement. Receiver Board Magnetic Shield B3H adjust operation freq. RX Coil Feedback Long distance Detection TX Coil Transmitter Board A6 adjust operation freq depend on distance. Magnetic Shield Excellent Service Team

Excellent Service Team Variety Power System Adjusting output power automatically depends on receiver’s need Receiver Board Magnetic Shield B3H always receive main voltage level RX Coil Detection High power need Raise charging energy Low power need Feedback TX Coil Transmitter Board A6 adjust power depend on B3H need Magnetic Shield Excellent Service Team

Excellent Service Team FOD(Foreign Object Damage) Protection Package for Transmitter and Receiver Main Chips Part Masking can’t block code Receiver Board Magnetic Shield RX Coil Feedback Charging Power Send out control code to stop Power from TX Metal Object Detection TX Coil Transmitter Board Magnetic Shield Excellent Service Team
