2 Test Setup

This section describes the test setup for the evaluation of the TLC6A598EVM board. Table 2-1 shows the EVM connectors and test points.

Table 2-1 TLC6A598EVM Connectors and Test Points
Reference Designator Function
J1 VCC
J2 GND for VCC
J3 VDD
J4 GND for VDD
J5 USB2ANY Connector
J6 Outputs connector for TLC6A598
J7 Outputs connector for Relays
TP1 Test point for VCC
TP2 Test Point for VDD
TP3, TP4, TP5 GND Test Point

The following equipment are required for the test setup:

  • A power supply 1 capable of supplying 5 V @ 0.3 A is required to supply VCC.
  • A power supply 2 capable of supplying 24 V @ 1 A is required to supply VDD.

To evaluate the TLC6A598EVM board, the USB2ANY interface adapter provided by TI is recommended here. Please download and install the USB2ANY Explorer Software on the computer.

Figure 2-1 shows the test bench setup for the evaluation of the TLC6A598EVM board.

Figure 2-1 TLC6A598EVM Test Bench Setup

Set the input voltage power supply 1 to 5 V and the current limit to 0.3 A. Turn off the power supply 1. Connect the power supply 1 to the J1 and J2 connectors with the positive terminal of the supply connected to VCC (J1) and the negative terminal of the supply connected to GND (J2). Set the input voltage power supply 2 to 24 V and the current limit to 1 A. Turn off the power supply 2. Connect the power supply 2 to the J3 and J4 connectors, with the positive terminal of the supply connected to VDD (J3) and the negative terminal of the supply connected to GND (J4).

Connect the USB2ANY with Edge cable to J5 and connect USB2ANY to the PC with USB cable.

With above setup and connections completed, turn on the power supply 1 and 2. Then open the USB2ANY Explorer Software and the software will show as Figure 2-2.
