Datasheet Summary
U211B2/ B3
Phase-Control Circuit
- General Purpose Feedback
Description
The integrated circuit U211B2/ B3 is designed as a phasecontrol circuit in bipolar technology with an internal frequency-voltage converter. Furthermore, it has an internal control amplifier which means it can be used for speed-regulated motor applications.
Features
D Internal frequency-to-voltage converter D Externally-controlled integrated amplifier D Overload limitation with a “fold back” characteristic D Optimized soft-start function D Tacho monitoring for shorted and open loop
