Atmel Corporation 

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

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

output. Motor control with load-current feedback and

overload protection are preferred applications.

D Internal supply-voltage monitoring

D Current requirement v 3 mA

D Temperature-compensated reference voltage

Applications

D Advanced motor control

D Grinder

D Drilling machine
