M51971L - MOTOR SPEED CONTROL

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

  • q Wide range of supply voltage.
  • 4.
  • 17.5V q Variation coefficient of supply voltage.
  • ±0.005%/V (standard) q Load variation coefficient.
