M51971L General Description
The M51971 is a semiconductor integrated circuit designed to control the motor rotating speed.
The built-in FG amplifier with high gain enables to use a wide range of rotating speed detector (FG detector).
Use of less external parts enables DC motors to be controlled with high precision.
