Features
Increasing the efficiency of motor rotation due to cutting
the electric current which doesn't contributing to rotation
Combining a GaAs Hall device and a driver IC in a
compact 8-pin SOP package
Operation in low magnetic flux density (10mT) due to
applied high sensitive Hall device
Built-in protection circuit, alarm output and automatic
restart circuit
GaAs Hall IC for Fan Motor
