IL2010B
PHASE CONTROL CIRCUIT FOR CURRENT FEEDBACK
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
