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.
