The integrated circuit, T2117, is designed as a zerovoltage switch in bipolar technology. It is used to control resistive loads at mains by a triac in zero-crossing mode.
A ramp generator T2117 allows power control function by period group control, whereas full-wave logic guarantees that full mains cycles are used for load switching.
