TDA1024 trigger equivalent, zero crossing triac trigger.
are:
* adjustable trigger pulse width
* adjustable hysteresis
* supplied from the mains
* provides supply fo r external temperature bridge
* protected.
The TDA1024 generates positive-going output pulses to trigger a triac. These trigger pulses coincide with the zero crossings of the mains voltage. This minimizes r.f. interference and transients on the mains supply.
Supply: V q c and R X (pins 8 and .
