U211B2/ B3
Phase Control Circuit - General Purpose Feedback
Description
The integrated circuit U211B2/ B3 is 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 speedregulated motor applications.
It has an integrated load limitation, tacho monitoring and soft-start functions, etc.
to realize sophisticated motor control systems.
