Description
The TIDA-01574 provides a reference design for low cost high efficiency power stealing for low cost smart thermostats and other building automation equipment. In general, power stealing enables to extend battery life of Wi-Fi enabled smart thermostats by drawing power from 24-V AC when the HVAC load is off. This power stealing TI design provides smooth and highly efficient way to steal power from 24-V AC without interrupting the operation of HVAC load. In this design, TPS2662 - 60V eFuse provides accurate current limiting and over voltage protection to enable highly efficient power stealing.
