3-phase motor driver
BA6438S
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
