Overview
U208B Open Loop Phase Control Circuit Description The integrated circuit, U208B, is designed as a phase control circuit in bipolar technology with internal supply-voltage monitoring.
As the voltage is built up, uncontrolled output pulses are avoided by internal monitoring.
Furthermore, it has internal-current and voltage synchronisation.
It is recommended as a low cost open-loop control.
Features D Automatic retriggering D Triggering pulse typ.
125 mA D Voltage and current synchronisation D Internal supply voltage monitoring D Current requirement ≤ 2.
