The TECA1-xV-xV-D is an electronic module designed for driving TECs (Thermo-Electric Coolers) with high stability in regulating the object temperature, high energy efficiency, zero EMI, and small package.
Selection Guide for TECA1 Series TEC Controllers
We can design and manufacture customized products based on customers' requirements.
-D: For example: TECA1-3V-1.3V-D. The controller comes with DIP package.
-S: For example: TECA1-3V-1.3V-S. The controller comes with SMT package.
U: For example: TECA1-5V-2.5V-DU. The controller only has cooling function, cannot do heating.
B: For example: TEC5V4A-DB. TEMP=Off @ SDNG=0.
S: For example: TECA1-5V-2.5V-DS. The controller has an internal pull down resistor on the SDN pin, as opposed to an internal pull up resistor.
H: For example: TECA1-3V-1.3V-DAH. Maximum|VTEMP − VTEMPSP| is ≤ 0.5mV.
LD: For example: TECA1LD-5V-4V-D. The controller comes with an internal compensation network.
-NT: For example: TEC5V4A-NT. There is no internal temperature range setting network.
-OP: For example: TECA1-5V-2.5V-D-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 500kΩ between the TEMPSP pin and a 1.5V voltage source, as opposed to the other controllers that do have this resistor.
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
