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.
Applications
VCR capstan motors, DAT capstan motors
Features
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.
Absolute maximum ratings (Ta = 25 C)
Recommended operating conditions
