The BA6871BS is a 3-phase, full-wave, pseudo-linear motor driver suited for VCR capstan motors. The IC has a torque ripple cancellation circuit to reduce wow and flutter, and an output transistor saturation prevention circuit that provides superb motor control over a wide range of current. The built-in motor power series regulator allows applications with low power consumption.

Features

1) 3-phase, full-wave, pseudo-linear driver system.

2) High performance torque ripple cancellation circuit.

3) Reversal braking by detecting the motor direction.

4) Saturation prevention circuit for high- and low-side output transistors.

5) Motor power supply series regulators.

6) Built-in circuit for output-to-GND short-circuit detection.

7) Two FG amplifiers.

8) Available in a SDIP 32-pin power shrink package.

Applications

3-phase VCR capstan motors
