Description

The STEVAL-IHT002V1 is a low-cost evaluation

board designed to replace existing mechanical

thermostats. While driving a compressor, the

evaluation board is also capable of driving the

RUN winding, replacing the PTC and directly

driving the START winding. Stall rotor detection is

also implemented. These functions are oriented

towards reducing total power consumption. The

evaluation board is based on the new low-cost, 8-

pin, 8-bit ST7Ultralite microcontroller (MCU),

which controls the entire process. The MCU is

equipped with programmable Flash memory, a 1

MHz internal clock source and runs 1 KB C-based

software. Although the evaluation board is

specially designed to drive small to mid-size

compressors, it is fully customizable and

adaptable to any other application where

thermostat or temperature control is required.
