The U2100B is a timer control circuit that uses bipolar technology. It has different mode selections (Zero voltage switch, Phase control, Relay control) and the output stage is triggered according to input conditions. It can be used as a power switch in triac applications for two or three wire systems.
The U2100B timer control circuit uses bipolar technology and offers selectable modes such as zero‑voltage switch, phase control, and relay control. It provides an adjustable and retriggerable tracking time, window monitoring for sensor inputs, and internal noise suppression.
The device is supplied in DIP8 and SO8 packages and can be used in two‑wire or three‑wire triac power‑switch applications, as well as in relay control circuits. Detailed electrical characteristics, absolute maximum ratings, and pin descriptions are provided for designers.
