Test Setup
6.1
Equipment
6.1.1
bqTESLA™ Receiver
Use the bq51013B-764 (HPA764) or bq51020EVM-520, a low-power Qi-compliant receiver.
6.1.2
Voltage Source
The input voltage source must provide a regulated DC voltage of 5 V and deliver at least 2.0-A continuous
load current; current limit must be set to 2 A.
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.
External Power Supply Requirements:
Nom Voltage: 5.0 VDC
Max Current: 2.0 A
Efficiency Level V
External Power Supply Regulatory Compliance Certifications: Recommend
selection and use of an external power supply which meets TI's required
minimum electrical ratings in addition to complying with applicable regional
product regulatory/safety certification requirements such as (by example) UL,
CSA, VDE, CCC, PSE, and so forth.
6.1.3
Meters
Monitor the output voltage at the bq51013BEVM-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 resistive load box that can be set to 10 kΩ, 10 Ω, and 5 Ω, power rating of at least 5 W; or an electronic
load that can be set to 0 mA, 500 mA and 1.0 A at 5 V.
6.1.5
Oscilloscope
Use a dual-channel oscilloscope with appropriate probes to observe the RECT signal at bq51013BEVM-
764 TP3 and other signals.
6.1.6
Recommended Wire Gauge
For proper operation, use 22-AWG wire when connecting the EVM to the input supply and the
bq51013BEVM-764 to the load.
6.1.7
