TECA1-5V-5V-D without internal compensation network is designed for driving thermoelectric cooler (TEC) with 2A ultra low noise current. When it is powered with 5V power supply, the output voltage is from 0V to 5V. In order to use TEC controller more easily, our company (ATI) has released an evaluation board TECEV104.
TECEV104 is made of a complete tuning and function circuit to drive TEC. Figure 1 is the physical photo of TECEV104. It not only can set the limit of output current and tune compensation network, but also set the internal temperature. It comes with an LED to indicate the temperature status of TEC.

TECA1-5V-5V-D is plugged in the center of the evaluation board. Pin voltages can be measured directly by probing connecting holes located on the left and right side of the module socket. Some of the pins can be connected with two holes on the evaluation board. The names of all the nodes are shown on the board. It is recommended to read this datasheet with the TECA1-5V-5V-D datasheet, so that it is more convenient to know the details about TEC controller module.
