描述 Description

DESCRIPTION
The M51970L is a semiconductor integrated circuit designed to control the motor rotating speed. Connection of the rotating speed detector (F-G detector) to the input keeps the motor rotating speed constant with high precision.
Connection of  an  appropriate power transistor to  the  output controls a wide range of DC motors.FEATURES
