Overview
Zero-Voltage Switch with adjustable Ramp
U217B
Description
The integrated circuit, U217B, is designed as a zerovoltage 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
