Zero Voltage Switch with Fixed Ramp
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
