MOTOR SPEED CONTROL
M51970L
MITSUBISHI <CONTROL / DRIVER IC>
PIN CONFIGURATION (TOP VIEW)
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
