Test Setup

6 Test Setup

6.1 Equipment

6.1.1 bqTESLA™ Receiver

Use the bq51013BEVM-764 or a Qi-compliant receiver to work with this EVM.

6.1.2 Voltage Source

The input voltage source must provide a regulated DC voltage of 5 V and deliver at least 2-A continuous

load current; current limit must be set to 3 A.

CAUTION

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: 3.0 A

Efficiency Level V

External Power Supply Regulatory Compliance Certifications: Recommend

selection and use of an external a 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 single load is required at 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

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.
