M51970L
MOTOR SPEED CONTROL
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
qWide range of supply voltage • • • • • • • • • • • • • 2.5 – 18V (-20 – +75˚C)
qVariation coefficient of supply voltage
• • • • • • • • • • • ±0.1% standard (4 – 15V)
qLoad variation coefficient • • • • • • • • • • • • • • • • • • • • • • • • • • ±0.1% standard
qTemperature coefficient of rotating speed
• • • • • • • • • • • • • • ±10 ppm/˚C (standard)
(-20 – +75˚C)
qThe built-in over-shoot prevention circuit keeps the over-shoot
low.
qDC drive system with minimum RFI
APPLICATION
Motor rotating control in the player, tape recorder, etc.
