Description
The IL2010B 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
Full wave current sensing
Mains supply variation compensated
Programmable load-current limitation
with over- and high-load output
Variable soft-start
Voltage and current synchronization
Automatic retriggering switchable
Triggering pulse typical 125 mA
Internal supply voltage monitoring
Current requirement
3 mA
Temperature compensated reference voltage
Applications
Advanced motor control
Grinder
Drilling machine
