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
●Wide range of supply voltage?????????????2.5–18V(-20–+75?C)
●Variation coefficient of supply voltage
