PRODUCT SPECIFICATIONS Intended Use/Category Wireless Charging H-Field Strength 50.21 dBuA/m@3m distance Frequency band(MHz) 110KHz-145KHz Modulation ASK Antenna type Coil Antenna Duty cycle(%) / Intended Use/Category NFC H-Field Strength 17.41 dBuA@3m distance Frequency band(MHz) 13.56MHz Modulation ASK Antenna type Coil Antenna Duty cycle(%) / IIIII. functional description The wireless charging input terminal VCC is connected to the 18V direct current. After the voltage is lowered by the BUCK circuit constituted by MOS tube Q1(RU30J30) and L3, it works in the full bridge circuit constituted by Q2(RU30J30) and Q3(RU30J30).The IC(CPS8100) sends a drive signal to control the Q2(RU30J30) upper and Q3(RU30J30) lower tubes and Q2(RU30J30) lower tubes and Q3(RU30J30) upper tubes to conduct alternately, so that an alternating voltage is obtained on the coil!Then through the electromagnetic induction to the receiving coil to get the voltage!The IC(CPS8100) detects current through resistor R9! NFC Product Overview Introduction The FM17550 is a highly integrated Transceiver IC for Contactless communication at 13.56MHz. The FM17550 Transceiver IC support Reader/Writer mode supporting ISO/IEC 14443A/B protocal. The FM17550’s internal transmitter part is able to drive a reader/writer antenna designed to communicate with ISO/IEC14443A/B cards and transponders without additional active circuitry. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO/IEC14443A/B compatible cards and transponders. The digital part handles the complete ISO/IEC 14443A/B framing and error detection. The FM17550 supports ISO/IEC14443A cards and transponders with transfer speeds from 106kbit/s to 424kbit/s in both directions. And can supports all layers of the ISO/IEC14443B reader/writer communication scheme, and provided that stardardized protocols, e.g. like ISO/IEC 14443-4 and/or ISO/IEC 14443B anticollision are correctly implemented. Features  Supports ISO/IEC 14443A/M1 reader/writer mode  Supports ISO/IEC 14443B reader/writer mode  ISO/IEC14443A 106kbit/s and higher transfer speed at 212kbit/s and 424kbit/s  Typical operating distance in reader/writer mode for communication to a ISO/IEC 14443A card up to 50mm (depending on the antenna size and tuning)  Supports host interfaces  SPI interface up to 10Mbit/s  I2C interface up to 400kbit/s in Fast Mode , and up to 3400kbit/s in High Speed Mode  Serial UART in different transfer speeds up to 1228.8kbit/s, framing according to the RS232 interface with voltage levels according pad voltage supply  Comfortable 64 byte send and receive FIFO-buffer  Flexible interrupt modes  Multiple low-power modes  Soft power down mode  Hard power down mode  Deep power down mode （typical 1uA）  Low Power external Card Detect (LPCD) at Reader/writer mode  Programmable timer  Internal oscillator to connect 27.12MHz quartz  Wide voltage supply: 2.2V ~ 3.6V  Dedicated transmitter voltage supply up to 5.5V  Integrated CRC Co-processor  Programmable I/O pins IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS WARNING When using this product, basic precautions should always be followed, including the following: • Read all the instructions before using the product. • To reduce the risk of injury, close supervision is necessary when the product is used near children. • DO NOT put fingers or hands into the product. • DO NOT use this product if the flexible power cord or output cable is frayed, has broken insulation, or any other signs of damage. • DO NOT allow anyone to ride the E-bike on his/her own unless he/she understands the proper operation and safety warnings.
