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