Zero-Voltage Switch with Adjustable Ramp
Description
The integrated circuit, T2117, 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 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
