T2117 Description
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 allows power control function by period group control, whereas full-wave logic guarantees that full mains cycles are used for load switching.
T2117 Key Features
