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. Figure 1 is the photo of an
actual TEC5V4A-D.
The module provides interface components for users to
configure desired object temperature range, i.e. set-point
temperature range ï¼› maximum voltage across TEC, i.e.
maximum TEC voltage; and the compensation network. The
compensation network compensates the high order thermal
load and thus stabilizes the temperature control loop.
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 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.
This is because the internal temperature measurement
network also uses this voltage as the reference, the errors in
setting the temperature and measuring the temperature cancel
with each other, setting the object temperature with higher
stability. This reference can also be utilized by an ADC
(Analog to Digital Converter), for the same reason, the
measurement error will also be independent of the reference
voltage, resulting in a more accurate measurement.
