No Preview Available ! Motor driver ICs 3-phase motor driver BA6871BS 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. FApplications 3-phase VCR capstan motors FFeatures 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 detec- tion. 7) Two FG amplifiers. 8) Available in a SDIP 32-pin power shrink package.
