Description

The integrated circuit U209B is designed as a phase-control circuit in bipolar technology with an internalfrequency-voltage  converter. Furthermore, it has aninternal open-loop amplifier which means it can be usedfor motor speed control with tacho feedback.

The U209B is a 14-pin shrink version of the U211B withreduced features. Using the U209B, the designer is ableto realize sophisticated as well as economic motor controlsystems.
