Product Summary

The U211B3 is an integrated circuit designed as a phase control 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. The U211B3 has an integrated load limitation, tacho monitoring and soft-start functions, etc. to realize sophisticated motor control systems.
