Low-Cost Phase-Control IC with Soft Start
U2008B
Description
The U2008B is designed as a phase-control circuit in
bipolar technology. It enables load-current detection as
well as mains-compensated phase control. Motor control
with load-current feedback and overload protection are
preferred applications.
Features
D Full wave current sensing
D Mains supply variation compensated
D Variable soft-start or load-current sensing
D Voltage and current synchronization
D Automatic retriggering switchable
D Triggering pulse typ. 125 mA
D Internal supply-voltage monitoring
D Current requirement v 3 mA
Applications
D Low-cost motor control
D Domestic appliance
