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
