U209B-M

U209B-M Datasheet


The integrated circuit U209B is designed as a phase-control circuit in bipolar technology with an internal frequency-to-voltage converter. The device includes an internal open-loop amplifier, which means it can be used for motor speed control with tacho feedback. The U209B is a 14-pin shrink version of the U211B with reduced features. Using the U209B, the designer is able to realize sophisticated as well as economic motor control systems.
