Timer Control for Triac and Relay
U2100B
Description
The timer control circuit, U2100B, uses bipolar technol-
ogy. It has different mode selections (Zero voltage switch,
Phase control, Relay control). The output stage is
triggered according to input conditions. It can be used in
triac application for two or three wire system as a power
switch.
Features
D Adjustable and retriggerable tracking time
D Window monitoring for sensor input
D Enable input for triggering
D Internal noise suppression (40 ms) and retrigger
blocking (640 ms)
D Two or three wire application
Package: DIP8, SO8
Applications
D Motion detectors
