PIN CONFIGURATION (TOP VIEW)
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.
FEATURES
qWide range of supply voltage 4 – 17.5V
qVariation coefficient of supply voltage
±0.005%/V (standard)
qLoad variation coefficient
±0.01% (standard, full load range)
qTemperature coefficient of rotating speed 7ppm/C (standard)
qBuilt-in high performance FG amplifier
APPLICATION
Motor rotating speed control in floppy disk driver, player, tape
recorder, car stereo, etc.
