BA6444FP

 3-phase, full-wave, pseudo-linear drive system.
Torque ripple cancellation circuit.
Forced brake circuit.
Output transistor (high- and low-sides) saturation prevention circuit.
FG and hysteresis amplifiers.
Thermal shutdown circuit.

The BA6444FP 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 a forced brake circuit that allows abrupt change of operational mode. The output transistor saturation prevention circuit provides superb torque control over a wide range of current. FG and hysteresis amplifiers are also built in.
