General 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.

Key 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.
