Figure-1 WCT-5W1COILTX Contents 1 Introduction 1 2 System Features 2 3 Getting Started 2 4 Cautions 3 WCT-5W1COILTX Reference Design System User Guide, Rev. 3.1 2 Freescale Semiconductor 2 System Features The WCT-5W1COILTX 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. 3 Getting Started WCT-5W1COILTX 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 LED1 will be blanking. Figure-2 WCT-5W1COILTX power on 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-5W1COILTX’s coil surface, then the transmitter will charge the equipment, under the normal charging states, LED1 will be turned on all the time, and LED2 will be blanking, and the RX will powered on the equipment normally. WCT-5W1COILTX User Guide Freescale Semiconductor 3 Figure-3 WCT-5W1COILTX 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. 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. • 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. WCT-5W1COILTX Reference Design System User Guide, Rev. 3.1 4 Freescale Semiconductor 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. To satisfy FCC RF exposure requirements for mobile and base station transmission devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operation at closer than this distance is not recommended. The antenna(s) used for this transmitter must not be co -located or operating in conjunction with any other antenna or transmitter.

Authority to Act as Agent Date: 2/25/2014 American Certification Body, Inc. 6731 Whittier Avenue Suite C110 McLean, VA 22101 Re: Obtaining FCC ID for Freescale Semiconductor, Inc.’s (Freescale) product WCT-5W1COIL Audix Technology(Shanghai)CO.,Ltd. is authorized to act as agent for Freescale Semiconductor, Inc. in connection with the above-referenced action. This authority is limited to actions required in order for Audix Technology(Shanghai)CO.,Ltd to obtain FCC ID RUN-WCT-5W1COILTX for Freescale product WCT- 5W1COIL. This authority does not extend to any other matters Freescale may have before the Commission. I certify that we are not subject to denial of federal benefits, that includes FCC benefits, pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. 862. Further, no party, as defined in 47 CFR 1.2002 (b), to the application is subject to denial of federal benefits, that includes FCC benefits. Attached to this letter is Freescale’s request that the designated sections of its application for FCC ID RUN- WCT-5W1COILTX be permanently treated as confidential and not disclosed publicly. Thank you. By: __________________________ R.N. Fielding (Signature 1 ) (Print name) Title: Director, Governmental and Regulatory Affairs On behalf of: Freescale Semiconductor Inc. (Company Name) Telephone: 512-895-4601 Encl.: a/s 1 Must be signed by applicant contact given for applicant on the FCC site, or by the authorized agent if an appropriate authorized agent letter has been provided. Letters should be placed on appropriate letterhead.

Request for Confidentiality Date: 2/25/2014 Subject: Confidentiality Request for: Freescale product WCT-5W1COIL to receive FCC ID RUN-WCT- 5W1COILTX Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit Short Term Permanent Block Diagrams Short Term External Photos Short Term Permanent* 2 Internal Photos Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Parts List & Placement/BOM Short Term Permanent Tune-Up Procedure Short Term Permanent Schematics Short Term Test Setup Photos Short Term Permanent* User’s Manual This request is being made in recognition of the fact that Freescale has spent substantial effort in developing this product, which is one of the first of its kind. Having the designated information easily available to Freescale competitors would negate the advantage Freescale has achieved by being early to market with this product. Losing this competitive advantage could adversely affect Freescale’s earnings from this product. Permanent Confidentiality: The applicant requests the exhibits designated above be treated as permanently confidential and withheld from public review as these materials contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of ___(specify number of days not to exceed 180) 3 ___ days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. NOTE for Industry Canada Applications: The applicant understands that until such time that IC distinguishes between Short Term and Permanent Confidentiality, either type of marked exhibit above will simply be marked Confidential when submitted to IC. Sincerely, By: Director, Regulatory & Governmental Affairs (Signature/Title 4 ) 2 The asterisked items (*) require further justification before permanent confidentiality will be allowed. These also currently require review by the FCC under their Permit-But-Ask policy before the grant is issued and can delay completion of an application. Further justification should be added to the note above. One such example for a potted device would be: “The EUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable damage to internal circuitry. See photographs exhibits that outline the device before and after potting.” 3 Please refer to http://acbcert.com/documents/misc-docs/Memo-Short-Term-Vs-Standard-Confidentiality.pdf for complete details. 4 - Must be signed by applicant contact given for applicant on the FCC site, or by the authorized agent if an appropriate authorized agent letter has been provided. Letters should be placed on appropriate letterhead.
