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.
Features
D Direct supply from the mains
D Current consumption
0.5 mA
D Very few external components
D Full-wave drive – no DC current component in the
load circuit
D Negative output current pulse typ. 100 mA –
short-circuit protected
