Overview
ing and F b ab ing IC’s fo ver ro Integrated Electronic Solutions 35 ars Ye Simple Zero-Crossing Triac Control Circuit with Adjustable Time-out 3 GENERAL DESCRIPTION The IES5521A is a derivative of the OM1654A, but offering the extra safety feature of a nominal 1 hour time-out.
This is a key safety requirement for a range of personal and home appliance applications.
The time-out function will stop the triac operation and thus prevent power from being applied to the heating elements.
Time-out can be accurately controlled from the AC supply frequency for a period of 1 hour (60Hz, or 71minutes at 50Hz), or can be adjusted by adding external resistor and capacitor components to set the fre...
