BA6438S Motor driver ICs 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 !Applications 3-phase VCR capstan motors !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.
