DESCRIPTIONS

The TECA1-xV-xV-DAH 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.

This module provides interface ports for users to set the desired object temperature, i.e. set-point temperature; the maximum output voltage across TEC; and the compensation network. The compensation network compensates the high order thermal load and thus stabilizes the temperature control loop.

Voltage difference between TEMP and TEMPSP is −0.02mV ~ 0.5mV, ten times lower than that of TECA1-xV-xV-D,4~5mV.

Selection Guide for TECA1-xV-xV-DAH Series TEC Controllers
We design and manufacture customized products based on customers' requirements.

Part Number Convention:

-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-3V-1.3V-DAH. 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.
