A MAINS-ZERO TRIAC-TRIGGERING CIRCUIT
The TDAI024 is a monolithic integrated circuit intended for use in ON/OFF control of triacs in static switching applications. It incorporates zero voltage point triggering to minimize radio interference. The TDAI024 is mainly intended for applications such as switching resistive loads and replacing mechanical thermostats in, for example:
- central heating installations,
- washing machine heaters,
- water heaters,
- smoothing irons.
