Motor driver ICs 3-phase motor driver BA6444FP 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. FApplications VCR capstan motors, DAT capstan motors FFeatures 1) 3-phase, full-wave, pseudo-linear drive system. 2) Torque ripple cancellation circuit. 3) Forced brake circuit. 4) Output transistor (high- and low-sides) saturation prevention circuit. 5) FG and hysteresis amplifiers. 6) Thermal shutdown circuit.
