TDA1023/T

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.

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
