TDA1023T

INTEGRATED CIRCUITS DATA SHEET TDA1023/T Proportional-control triac triggering circuit Product specification Supersedes data of August 1982 File under Integrated Circuits, IC02 May 1991 Philips Semiconductors Product specification Proportional-control triac triggering circuit 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 GENERAL DESCRIPTION APPLICATIONS Panel heaters Temperature control TDA1023/T 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 SYMBOL VCC VZ I16(AV) tw Tb -IOH(1) Tamb Note 1. Negative current is defined as conventional current flow out of a device. A negative output current is suited for positive triac triggering.
