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