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
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
D Simple power control
D Ramp generator
D Reference voltage
Applications
D Full-wave power control
D Temperature regulation
D Power blinking switch
