Overview

The LB1687M is a 3-phase brushless motor driver IC ide­ally suited for use in VCR capstan motor, drum motor drive

applications.

Features and Functions

• 120° voltage linear type.

• Soft switching type eliminating noises caused by current
switching and making the value of external capacitors
smaller (comparable to those of chip capacitors).

• On-chip FG amplifier.

• On-chip thermal shutdown circuit.

• FG signal can be used to detect the rotational speed of a
motor so that the hall amplifier gain is changed in two
steps, thus reducing torque ripple and noise.

• Motor drivable at voltage down to motor supply voltage
5V.
