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.  
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).  
4) Output transistor (high-and low-sides) saturation  
prevention circuit
