Phase Control Circuit for Current Feedback
U2010B
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.
Features
D Full wave current sensing
D Mains supply variation compensated
D Programmable load-current limitation
with over- and high-load output
D Variable soft-start
D Voltage and current synchronization
D Automatic retriggering switchable
D Triggering pulse typical 125 mA
Package: DIP16, SO16
D Internal supply voltage monitoring
vD Current requirement 3 mA
D Temperature compensated reference voltage
Applications
D Advanced motor control
D Grinder
D Drilling machine
