Description

The BA6446FP and BA6446FM are 3-phase, full-wave, pseudo-linear motor drivers suited for VCR capstan motors. The
IC has a torque ripple cancellation circuit to reduce wow and flutter, a forced brake circuit that allows abrupt change of operational mode, and an output transistor saturation prevention circuit that provides superb motor control over a wide range of currents. The IC also contains FG and hysteresis amplifiers.
