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.
