U2010B
U2010B Phase-Control IC
– Current Feedback & Overload Protection
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.
