Equipment
6.1.1
bqTESLA™ Receiver
Use the bq51013AEVM-764, -765 or Qi-compliant receiver to work with this EVM.
6.1.2
Voltage Source
Input voltage source must provide regulated dc voltage of 12 V and be able to deliver at least 1.0 A
continuous load current; the current limit must be set to 2.0 A.
continuous load current; the current limit must be set to 2.0 A.
CAUTION
Safety Considerations of Voltage Source: To help assure safety integrity of
the system and minimize risk of electrical shock hazard, always use a power
supply providing suitable isolation and supplemental insulation (double
insulated).

Compliance to IEC 61010-1, Safety Requirements for Electrical
Equipment for Measurement, Control and Laboratory Use, Part 1, General
Requirements, or its equivalent is strongly suggested, including any required
regional regulatory compliance certification approvals. Always select a power
source that is suitably rated for use with this EVM as referenced in this user
manual.

6.1.3
Meters
Monitor the output voltage at the bq51013AEVM-764 test point, TP7, with a voltmeter. Monitor the input
current into the load with an appropriate ammeter. You can also monitor the transmitter input current and
voltage, but the meter must use the averaging function for reducing error due to communications packets.

6.1.4
Loads
A single load is required for 5 V with a maximum current of 1 A. The load can be resistive or electronic.
6.1.5
Oscilloscope
Use a dual-channel oscilloscope with appropriate probes to observe the COMM_DRV signal at
bq51013AEVM-764 TP3 and other signals.

6.1.6
Recommended Wire Gauge
For proper operation, 22-AWG wire is recommended when connecting the bq500410AEVM-045 to the
input supply and the bq51013AEVM-764 to the load.

6.2
Equipment Setup
•
With the power supply OFF, connect the supply to the bqTESLA™ transmitter.
•
Connect the Vin positive power source to J1, and connect the negative terminal of the V
IN
source to J2.
•
Do not place the bqTESLA™ receiver on the transmitter. Connect a load to J3 with a return to J4,
monitor current through load with an ammeter, and monitor the current to load at TP7. All voltmeters
must be Kelvin connected (at the pin) to the point of interest.
