Application note
STEVAL-IHT002V1
Intelligent thermostat for compressor based on ST7Ultralite MCU

Introduction
The STEVAL-IHT002V1 is a very low-cost evaluation board designed with the intent to
replace the existing mechanical thermostat.
While driving a compressor, the evaluation board is able to drive the RUN winding, replace
the PTC and drive directly the START winding too. Stall rotor detection is also implemented.
Both functions are oriented to reduce the total power consumption.
