Description
The monolithic integrated bipolar circuit, TEA1024/TEA1124 is a zero voltage switch for triac control in domestic equipments. It offers not only the control of a triac in zero crossing mode but also the possibility of power control. This is why the IC contains a mains synchronized ramp generator with 640 ms (1280 ms) duration (50 Hz). It is suitable for a typical load of 750 W (1000 W) meeting the Flicker Standard. (values in brackets relate to TEA1124.)
