The MAX8521 evaluation kit (EV kit) is an assembled
and tested PC board that implements a switch-mode
driver for a Peltier thermoelectric cooler (TEC) module.
The device operates from a single 3V to 5.5V supply
and provides a bipolar ±1.5A output to the module.
A potentiometer, DAC, or external source generates a
DC temperature set-point voltage. Thermal feedback
from the TEC module is compared to the set-point
voltage to generate the TEC current control signal. The
MAX8521 accurately regulates the TEC current based
on this signal. When using the DAC, the EV kit connects
to the parallel port of a computer running Windows® 95,
98, or 2000. Software, included with the EV kit,
provides a quick and easy method to control the DAC.
To evaluate the MAX8520ETP or MAX8521ETP (QFN
version), refer to the MAX8520 evaluation kit.
Note: Windows 2000 requires the installation of a
driver located on the CD.
