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 swithching, phase control, time proportional control.
Parametrics
TCA280A absolute maximum ratings: (1)supply voltage, d.c, Vcc: 14.4V; (2)supply current, Icc: 1mA; (3)output current, Ioh: 200mA; (4)output pulse width, tw: 190us; (5)power dissipation, unloaded, p: 15mW; (6)operating ambient temperature range, Tamb: -20 to +80℃.
Features
TCA280A features: (1)adjustable proportional range; (2)adjustable hysteresis; (3)adjustable firing burst repetion time; (4)adjustable pulse width; (5)supplied from the mains; (6)provides supply for external temperature bridge; (7)low supply current, low dissipation.
