2 / 19 page May 1991 2 Philips Semiconductors Product specification Proportional-control triac triggering circuit TDA1023/T FEATURES • Adjustable width of proportional range • Adjustable hysteresis • Adjustable width of trigger pulse • Adjustable repetition timing of firing burst • Control range translation facility • Fail safe operation • Supplied from the mains • Provides supply for external temperature bridge APPLICATIONS • Panel heaters • Temperature control GENERAL DESCRIPTION The TDA1023 is a bipolar integrated circuit for controlling triacs in a proportional time or burst firing mode. Permitting precise temperature control of heating equipment it is especially suited to the control of panel heaters. It generates positive-going trigger pulses but complies with regulations regarding mains waveform distortion and RF interference. QUICK REFERENCE DATA Note 1. Negative current is defined as conventional current flow out of a device. A negative output current is suited for positive triac triggering. ORDERING INFORMATION Note 1.
