The BA6438S 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 switching regulator allows applications with low power consumption

FEATUREs
1) 3-phase, full-wave, pseudo-linear drive system.
2) Torque ripple cancellation circuit.
3) Reversal brake based on the detection of motor direction.
4) Output transistor (high-and low-sides) saturation prevention circuit
5) Motor power switching regulator with oscillation circuit.
6) Output-to-GND short-circuit detection.
7) Available in SDIP 24-pin power package (with radiation fins).
