1. Description
The timer control circuit U2100B uses bipolar technology. It has different mode selec-
tions (zero voltage switch, phase control and relay control). The output stage is
triggered according to input conditions. It can be used in triac application for two- or
three-wire systems as a power switch.
Adjustable and Retriggerable Tracking Time
Window Monitoring for Sensor Input
Enable Input for Triggering
Internal Noise Suppression (40 ms) and Retrigger Blocking (640 ms)
Two- or Three-wire Applications
Motion Detectors
Touch Sensors
Timers
Timer Control
for Triac and
Relay

... 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 applications for two-wire systems as power switch (the load in series to the switch), where the supply voltage for the con- trol unit is gained from the remaining phase angle ( Figure 3-1 ...
