6.3.9
Foreign Object Detection (FOD)
The bq50002 EVM supports FOD in order to meet the requirements of the WPC V1.2 specification.
Continuously monitoring input power, known losses, and the value of power reported by the receiver
device being charged, the bq500511 can estimate how much power is unaccounted for and presumed lost
due to metal objects placed in the wireless power transfer path. If this unexpected loss exceeds the
threshold set by the FOD resistors, a fault is indicated and power transfer is halted.
Three key measurements for the TX FOD calculation:
• Input Power – Product of input voltage and current. Input voltage is measured at BQ500511 pin 9
though R13 and R14. Input current is measured using sense resistor R18 at BQ50002 pin 29 and 30.
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, R26. This calculation changes with
external component changes in the power path such as resonant capacitors and TX coil. Recalculation
of R26 and R27 is required.
• Receiver Reported Power – The receiver calculates and reports power it receives in the message
packet Received Power Packet.
The FOD threshold on the EVM is set to 400 mW when R27 is set to 100 kΩ. Increasing R27 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 a unit manufactured
by Avid® Technology. Contact Texas Instruments for the FOD calibration procedure for the bq50002.

Thermal Performance
This section shows a thermal image of the bq50002EVM-607. A 1000-mA load is used at the receiver
output, bq51013BEVM-764. Output power is approximately 5 W, 1 A at 5 V. The highest temperature point

bq50002EVM-607 Assembly Drawings and Layout
Figure 8 through Figure 11 show the design of the bq50002EVM 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 on the top and bottom layers to allow the user to easily
view, probe, and evaluate bq50002 analog frontend IC and bq500511 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 (bq50002EVM-607).
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 bq50002 GND pins and filter
capacitor returns 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.

Concerning EVMs Including Detachable Antennas:
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser)
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type
and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types
listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited
for use with this device.
