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.
•Internal supply voltage monitoring
Features
•Current requirement 3 mA
