Product Summary

The TCA280A is a bipolar integrated circuit delivering positive pulses for triggering a triac or a thyristor. The flexibility of the circuit makes it suited for a great variety of applications, such as: synchronous on/off switching, phase control, time-proportional control, temperature control, motor speed control.

Parametrics

TCA280A absolute maximum ratings: (1)Input voltage, all inputs Vi max.: 17V; (2)Differential input voltage between IC+ and IC ViD max.: 7V; (3)Input current, all inputs Ii max.: 10mA; (4)Total power dissipation Ptot: see Fig.3; (5)Storage temperature range Tstg: -55 to + 125°C; (6)Operating ambient temperature range Tamb: -20 to + 80°C.

Features

TCA280A features: (1)adjustable proportional range; (2)adjustable hysteresis; (3)adjustable firing burst repetition time; (4)adjustable pulse width; (5)supplied from the mains; (6)provides supply for external temperature bridge; (7)low supply current, low dissipation.
