www.DataSheet4U.com T2117 Zero-Voltage Switch with Adjustable Ramp 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. Features D Direct supply from the mains D Current consumption ≤ 0.5 mA D Very few external components D Full-wave drive – no DC current component in the load circuit D Negative output current pulse typ.
