TDA1023 Datasheet Proportional-control Triac

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: 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.

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.

Key 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.
