U211B2
Overview
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.
- Internal frequency-to-voltage converter
- Externally-controlled integrated amplifier
- Overload limitation with a “fold back” characteristic
- Optimized soft-start function
- Tacho monitoring for shorted and open loop
