General Description
The monostable integrated power-control circuit U2100B can be used according to the
mode selection in relay or triac applications. In addition, it can be used in triac applica-
tions for two-wire systems as power switch (the load in series to the switch), where the
supply voltage for the control unit is gained from the remaining phase angle
(α_min operation).
