APPLICATIONS

Driving TECs in regulating the object's temperature

The TEC5V4A-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.

It provides these functions: thermistor T-R curve linearization, temperature measurement and monitoring, temperature control loop status indication, TEC voltage monitoring, power up delay, and shut down.

The TEC5V4A-D comes with a high stability low noise 3.0V voltage reference which can be used for setting the desired object's temperature by using a POT (Potentiometer) or a DAC (Digital to Analog Converter). When using this reference for setting the set-point temperature, the set-point temperature error is independent of this reference voltage.

Suffix Definition:

-D: For example: TEC5V4A-D. The controller comes with DIP package.

A: For example: TEC5V4A-DA. TEMP=On @ SDNG=0.

B: For example: TEC5V4A-DB. TEMP=Off @ SDNG=0.

H: For example: TEC5V4A-DAH. Maximum|VTEMP − VTEMPSP| is ≤ 0.5mV.

-NT: For example: TEC5V4A-NT. There is no internal temperature range setting network.
