  • Product Details

    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.
