1 Applications

The bq500212AEVM-550 evaluation module demonstrates the transmitter portion of the bqTESLA™

wireless power system. This transmitter EVM is a complete transmitter-side solution that powers a

bqTESLA™ receiver. The EVM requires a single 5-V power supply capable of up to 2 A to operate and

combines the transmitter electronics, input power socket, LED indicators, and the transmitting coil on the

single printed-circuit board (PCB). The open design allows easy access to key points of the electrical

schematic.

This EVM has the following features:

• WPC 1.1 Foreign Object Detection (FOD) and WPC 1.0 Parasitic Metal Object Detection (PMOD)

• Dynamic Power Limiting™ (DPL) allows operation from a 5-V supply with limited current capability (for

example, a USB port)

• 5-V input power which is really available

• Transmitter-coil mounting pad providing the correct receiver interface

• Compact power section design using the CSD97376 NexFET power stage

• Standard WPC A11-type transmitter coil with no magnet

• LED indicates power transfer or power fault state

6.2.1 Equipment Setup Diagram

The diagram in Figure 4 shows the test setup.

Figure 4. Equipment Setup

6.2.2 EVM Procedures

This section guides the user 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 blue power LED, D1, illuminates. Status LEDs D7, D9 and D5 are OFF

until the power transfer starts.

Apply the scope probe to the test point, TP1, 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.

6.2.2.2 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, D5,

flashes green, indicating that communication between the transmitter and the receiver is established and

that power transfer has started.

• The status LED, D5, flashes a green light during power transfer.

• Typical output voltage is 5 V, and the output current range is 0 mA to 1 A.

• Observe a continuous sine-wave on the test point TP1 when power transfer is active; the frequency is

between 110 kHz and 205 kHz.

• Make tests and measurements applicable to a normal 5-V power supply.

Test Setup

6.2.2.3 Efficiency

To measure system efficiency, measure the output voltage, the 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 (C30-COG but C29, C28, and C27 - X7R). Also shown is efficiency with C30, C29,

C28, and C27 all capacitors COG type.

Figure 5. Efficiency versus Power, bq500212AEVM-550 Transmitter and HPA764 Receiver

6.2.2.4 Efficiency Improvements

Efficiency improvements can be made with component changes. The EVM uses an integrated power

stage device that combines both the driver and two MOSFETs into one package, CSD97376. Similar

devices with lower RDSon MOSFETs are available. The CSD97374 reduces RDSon by about 50% and

improves efficiency by 2% to 4%. This device is pin-to-pin compatible and is a drop in replacement.

To reduce cost, the EVM uses a mix on COG and X7R capacitors for the resonant capacitors, C28, C29,

C30 and C27. X7R is lower cost but has higher ESR which results in higher loss. If all COG capacitors are

used, efficiency increases by 2% to 4%.

Note that changing the efficiency of the unit and reducing loss (or increasing loss) changes the FOD

performance and may require re-calibration. This would require FOD_CAL resistor, R99 to change along

with FOD_Threshold resistor, R24. FOD Calibration procedure would need to be repeated.

6.2.2.5 Dynamic Power Limiting

Dynamic Power Limiting (DPL) allows operation from a 5-V supply with limited current capability. Input

voltage is monitored at Pin 46 though a voltage divider network. When input voltage decreases to 4.2 V,

the operating point is adjusted to reduce load and increase input voltage to 4.5 V.

6.2.2.6 Thermal Protection, NTC

Thermal protection is provided by an NTC resistor connected to JP1. At 1 V on the sense side (U1-2), the

thermal fault is set, and the unit is shut down, The status LED, D5, illuminates red. The typical resistor

value for fault is 850 Ω. The system tries to restart in 5 minutes.

6.2.2.7 Foreign Object Detection

The bq500212A EVM incorporated 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

R24, 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 46 though R10

and R11. Input current is measured using sense resistor R32 and current sense amp U7. Both

measurements need to 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, R99. This calculation changes with

external component changes in the power path such as MOSFETs, resonate capacitors, and TX coil.

Recalculation of R99 and R24 will be 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 350 mW, R24 is set to 48.7 kΩ. Increasing R24 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 unit manufactured by Avid®Technology. Contact Texas Instruments for the

Foreign Object Detection Calibration Procedure for bq500212A.

6.2.2.8 WPC Certification

The bq500212AEVM-550 was tested and certified to WPC version 1.1.1, July 2013.

7 bq500212AEVM-550 Assembly Drawings and Layout

Figure 6 through Figure 11 show the design of the bq500212AEVM PCB. The EVM has been designed

using a 4-layer, 2-oz, copper-clad circuit board 13.2 cm × 7.24 cm with all components in a 4.0-cm x 5.0-

cm active area on the top side and all active traces to the top and bottom layers to allow the user to easily

view, probe, and evaluate the bq500212A 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 bq500212A GND 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 (0.93 in or 2.4 mm) is the z-gap thickness for the transmitter.

Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such

as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices

which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate

Assurance and Indemnity Agreement.

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other

changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest

issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and

complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale

supplied at the time of order acknowledgment.

TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms

and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary

to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily

performed.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and

applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information

published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or

endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration

and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered

documentation. Information of third parties may be subject to additional restrictions.

Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service

voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

TI is not responsible or liable for any such statements.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements

concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support

that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which

anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause

harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use

of any TI components in safety-critical applications.

In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to

help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and

requirements. Nonetheless, such components are subject to these terms.

No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties

have executed a special agreement specifically governing such use.

Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in

military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components

which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and

regulatory requirements in connection with such use.

TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of

non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
