General Description
Monostable integrated power control circuit, U2100B,
can be used according to mode selection in relay’s or
triac’s applications. Beyond that, it can be used in triac-
application for two wire system as power switch, (being
the load in series to the switch) whereas the supply
voltage for the control unit is gained from phase rest angle
(
min
-operation).

Figure 3. Three wire circuit
For three wire switch, two modes of operations are
possible:
Zero voltage switch operation for triac control
Mode Selection Pin 4 and Supply Voltage
Pin 2
Static operation for relay control
Operation modes can be selected by external voltage at
the sync. input Pin 4 (clamping). Mode selection deter-
mines the current requirement of driver stage for relay’s
or triac’s and hence the selection of supply voltage.
