Overview
U2010B Phase Control Circuit for Current Feedback Description The U2010B is designed as a phase-control circuit in bipolar technology.
It enables load-current detection and has a soft-start function as well as reference voltage output.
Motor control with load-current feedback and overload protection are preferred applications.
