STEVAL-IHT002V1 Thermostat control demonstration board for refrigerators, based on the ST7Lite39

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.

技术特性
