Equipment Setup 6.2.2 EVM Procedures This section is provided as a guide through a few general test procedures to exercise the functionality of the presented hardware. Some key notes follow: 6.2.2.1 Start-Up No Receiver Turn on VIN, and observe that the green power LED, D1, illuminates. Status LEDs D2, D8 and D9 are OFF until the power transfer starts. Apply the scope probe to test point, TP18, and observe single-pulse bursts approximately every 500 ms. This is a digital ping to begin communications with a receiver placed on the TX coil. SLVUA40A - March 2014 - Revised January 2015 Submit Documentation Feedback bq500414Q bqTESLA Wireless Power TX EVM Copyright (c) 2014-2015, Texas Instruments Incorporated 13 Test Setup 6.2.2.2 www.ti.com Apply Receivers Place the bq51013BEVM-764 EVM on the top of the transmitting coil. Align the centers of the receiving and transmitting coils across each other. In the next few seconds, observe that the status LED, D6, flashes green, indicating that communication between the transmitter and the receiver is established and that power transfer has started. * The status LED, D8, flashes a green light during power transfer. * Typical output voltage is 5 V, and the output current range is 0 mA to 1 A. 6.2.2.3 Efficiency To measure system efficiency, measure the output voltage, output current, input voltage, and input current and calculate efficiency as the ratio of the output power to the input power. Connect voltage meters at the input and output of TX and RX (see Figure 4). Average the input current; the comm pulses modulate the input current, distorting the reading. See Figure 5 for efficiency. Figure 5 shows efficiency with standard EVM. This shows the efficiency from transmitter input to receiver output. The input power SEPIC converter is included in this circuit and loss is higher due to power loss in two converters. For this test, an input voltage of 13.6 V was used. Figure 5. Efficiency versus Power, bq500414QEVM-629 Transmitter and HPA764 Receiver 6.2.2.4 Efficiency Efficiency is affected by changes in the power section. Higher RDSON MOSFET increases loss. This is a design decision and a trade off between cost and performance. Parts selected for the EVM design are optimized for efficiency. Note that changing the efficiency of the unit and reducing loss (or increasing loss) changes the FOD and the PMOD performance and may require re-calibration. This would require the FOD_CAL resistor (R52) to change along with FOD_Threshold resistor (R3) and PMOD resistor (R22). The FOD and PMOD calibration procedure must be repeated. 6.2.2.5 Input Power DC / DC Converter To support the input voltage range for an automotive application, an optional wide input voltage converter is installed on the board. The TPS40210 is configured as a Single-Ended Primary-Induction Converter (SEPIC) providing a 12-V output from an input voltage that can be above and below 12V. 6.2.2.6 EMI Shield The EVM is designed to support an EMI Shield above the coils to reduce emissions. The shield, PWR633, is a comb-type filter that is effective between 100 kHz and 2 MHz. 14 bq500414Q bqTESLA Wireless Power TX EVM SLVUA40A - March 2014 - Revised January 2015 Submit Documentation Feedback Copyright (c) 2014-2015, Texas Instruments Incorporated Test Setup www.ti.com To install the shield: Remove clear plastic cover and hardware. Install the PWR633 filter using metal hardware provided. The filter is grounded though the metal hardware to the TX coil area. Circuit changes: EMI_Shield select pin 21 ground = no shield, high(3.3V) = shield FOD_CAL R52 no shield = 16.2 k, shield = 8.06 k NOTE: if ONLY EMI behavior is to be evaluated with the addition of the shield, then circuit changes are not required. 6.2.2.7 Configuration Resistor Some functions can be configured by an external resistor pull up and connections, see the data sheet (SLUSBE4) for more info: 1. Coil Select R58 and R57, configure for type of coil used 2. Shield / no shield Pin 21, configure for shield or no shield 3. Operating freq pin 26, R70 and R69, option to reduce operating range 6.2.2.8 Thermal Protection, NTC Thermal protection is provided by an NTC resistor network is connected to pin 2. At 1 V on the sense side (U10-2), the thermal fault is set, and the unit is shut down, The status LED, D7, illuminates red. The system tries to restart in 5 minutes. 6.2.2.9 Foreign Object Detection The bq500414Q EVM incorporated the Foreign Object Detection (FOD) call in WPC 1.1. Power loss is calculated by comparing the power sent to the receiver (RX) with the power the RX reported receiving, less know power loss. The transmitter determines the power sent to the RX by measuring input power and calculating internal losses. The RX measures the power it received and also calculates losses. The RX sends this information to the driver (TX) in a digital word, message packet. Unaccounted for power loss is presumed to be a foreign object on the charging pad. Should this lost power exceed the threshold set by R34, a FOD fault is set and power transfer is stopped. Three key measurements for the TX FOD calculation: * Input Power - Product of input voltage and current. Input voltage is measured at pin 45 though R33 and R31. Input current is measured using sense resistor R64 and current sense amp U9. Both measurements must be very accurate. * Power Loss in Transmitter - This is an internal calculation based on the operating point of the transmitter. The calculation is adjusted using FOD_Cal resistor, R52. This calculation changes with external component changes in the power path such as MOSFETs, resonate capacitors, and TX coil. Recalculation of R52 and R3 is required. * Receiver Reported Power - The receiver calculates and reports power it receives in the message packet "Received Power Packet (0X04)". The FOD threshold on the EVM is set to 550 mW, R3 is set to 86.6 k. Increasing R3 increases the threshold and reduces the sensitivity to foreign objects. This loss threshold is determined after making a measurement of transmitter performance using a FOD calibration receiver similar to the unit manufactured by Avid(R) Technology. Contact Texas Instruments for the FOD calibration procedure for bq500414Q. 6.2.2.10 WPC Certification The bq500414QEVM-629 was tested and certified to WPC version 1.2.

The EVM has been designed using a 4-layer, 2-oz, copper-clad circuit board 15.24 cm x 13.335 cm, but components fit into an 8cm x 5.0-cm area on the top side. All parts are easy to view, probe, and evaluate the bq500414Q control IC in a practical application. Moving components to both sides of the PCB or using additional internal layers offers additional size reduction for space-constrained systems. Gerber files are available for download from the EVM product folder. A 4-layer PCB design is recommended to provide a good low-noise ground plane for all circuits. A 2-layer PCB presents a high risk of poor performance. Grounding between the bq500414Q GND EPAD, pin 47, 36, and 32 and filter capacitor returns C19, C1, C5, and C3 should be a good low-impedance path. Coil Grounding - A ground plane area under the coil is recommended to reduce noise coupling into the receiver. The ground plane for the EVM is slightly larger than the coil footprint and grounded at one point back to the circuit area. Note: The clear plastic cover thickness (0.093 in or 2.4 mm) is the z-gap thickness for the transmitter. Components marked `DNP' should not be populated, and may not be listed in the bill of materials. Figure 6.
