Power Drivers for Peltier TEC Modules
Applications Information
The MAX1968/MAX1969 typically drive a thermoelectric
cooler inside a thermal control loop. TEC drive polarity
and power are regulated based on temperature informa-

tion read from a thermistor, or other temperature-mea-
suring device to maintain a stable control temperature.
Temperature stability of 0.01 ° C can be achieved with
carefully selected external components.
There are numerous ways to implement the thermal
loop. Figures 1 and 2 show a design that employs preci-

sion op amps, along with a DAC or potentiometer to set
the control temperature. The loop may also be imple-
mented digitally, using a precision A/D to read the ther-
mistor or other temperature sensor, a microcontroller to
implement the control algorithm, and a DAC (or filtered
PWM signal) to send the appropriate signal to the
MAX1968/MAX1969 CTLI input. Regardless of the form
taken by the thermal control circuitry, all designs are
similar in that they read temperature, compare it to a
set-point signal, and then send an error-correcting sig-
nal to the MAX1968/MAX1969 that moves the tempera-
ture in the appropriate direction.
