... Current Requirement Description The integrated circuit U211B is designed as a phase-control circuit in bipolar technol- ogy with an internal frequency-to-voltage converter. The device includes an internal control amplifier which means it can be used for speed-regulated motor applications. Amongst others, the device features integrated load limitation, tacho monitoring and soft-start functions, to realize sophisticated motor control systems ...
