TECA1 Series TEC Controllers

Suffix Definition:

U: The controller only has cooling function, can not do heating. For example: TECA1-5V-2.5V-DU.

S: The controller has an internal pull down resistor on the SDN pin, as opposed to an internal pull up resistor. For example: TECA1-5V-2.5V-DS.

-OP: The controller does not have the two pulling - to -the- middle resistors on the TEMPSP pin, as opposed to the controllers that do have these two resistors. See the datasheet for details. The controller does not have the resistor of 500KOhm between the TEMPSP pin and a 1.5V voltage source, as opposed to the other controllers that do have this resistor. For example: TECA1-5V-2.5V-D-OP.

LD: The controller with an internal compensation network.

Note:

Evaluation Board, TECEV104, is available for TEC controllers TECA1-xV-xV-D, which can be used for achieving the following functions:

1. Setting maximum output voltage

2. Setting set-point temperature

3. Monitoring output voltage

4. Monitoring acutal thermal load temperature

5. Tuning the compensation network so as to match thermal load
