Figure-1 WCT-5WTXMULTI Contents 1 Introduction 1 2 System Features 2 3 Getting Started 2 4 Cautions 3 WCT-5WTXMULTI Reference Design System User Guide, Rev. 2 2 Freescale Semiconductor 2 System Features The WCT-5WTXMULTI reference board has following features: • Reference design compliant with low power WPC Qi version 1.1 Specification. • Integrated digital demodulation in chip. • Support multiple types Rx modulation signals (AC capacitor, AC resistor and DC resistor). • Support FOD. Support four types of Foreign Object protection. • Support Qi 1.1 receiver with 5 V DC@1A output power capability. • Super low standby power by Freescale touch technology. • Full bridge topology with freqency modulation power control strategy. • LED for RX and TX alignment indication. • Input voltage/current, coil current sensing for protection. • Free position charging. 3 Getting Started WCT-5WTXMULTI is easy to use, and can convenience to charging the mobile equipment that support the Qi wireless charging, below is the detail step to power up the system and use. Step 1: power on the Transmitter, plug the 5V adaptor to the AC power line, and plug the adaptor USB port to the transmitter input port, and the LED2 will be blanking. Figure-2 WCT-5WTXMULTI powered on WCT- 5WTXMULTI User Guide Freescale Semiconductor 3 Step 2: Place the wireless charging RX or some equipment that support the Qi wireless charger(such as cell phone, battery and so on ) on the WCT-5WTXMULTI’s coil surface, then the transmitter will charge the equipment, under the normal charging states, LED2 will be turned on all the time, and LED1 will be blanking, and the RX will powered on the equipment normally. Figure-3 WCT-5WTXMULTI charging the equipments Others Indicates: when the Transmitter get the end power communication information, it will stop the charging and wait until the RX is removed, under this states LED1 will be turned off, and LED2 will be turned on all the time. When some fault found, the transmitter will turn off LED1, and turn on LED2 until the fault is removed, fault include the FOD fault, OVP, OTP and so on. DPL mode: when the transmitter is powered by the limited power USB port, the sytem maybe enter the DPL mode, the cell phone will be charged with limited power. 4 Cautions • This device has been tested and found to comply with the limits pursuant to Part 18 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. • If this equipment does cause harmful interference to other electronic equipments, which can be determined by turning the equipment OFF and ON, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the equipment • Increase the separation • In order to use the equipment safely，please don’t open the case when powered on，and don’t touch the PCB and components with hand. WCT-5WTXMULTI Reference Design System User Guide, Rev. 2 4 Freescale Semiconductor • Don’t place some metal things between the TX surface and the RX surface, otherwise the metal things will be heated, it the temperature is too high, the Transmitter will shut down for protection. This device complies with Part15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.
