U217B  
Zero-Voltage Switch with Adjustable Ramp  
Description  
The integrated circuit, U217B, is designed as a zero- A ramp generator allows power control function by  
voltage switch in bipolar technology. It is used to control period group control, whereas full-wave logic guarantees  
resistive loads at mains by a triac in zero-crossing mode. that full mains cycles are used for load switching.  
Features  
Simple power control  
Direct supply from the mains  
Ramp generator  
Current consumption 0.5 mA  
Reference voltage  
Very few external components  
Applications  
Full-wave drive – no DC current component in the  
Full-wave power control  
load circuit  
Temperature regulation  
Negative output current pulse typ. 100 mA –  
short-circuit protected  
Power blinking switch
