Overview
Motor driver ICs 3-phase motor driver BA6870S The BA6870S 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 an output transistor saturation prevention circuit that provides superb motor control over a wide range of current.
The built-in motor power series regulator allows applications with low power consumption.
FApplications 3-phase VCR capstan motors FFeatures 1) 3-phase, full-wave, pseudo-linear driver system.
2) High performance torque ripple cancellation circuit.
3) Reversal braking by detecting the motor direction.
4) Saturation prevention circuit for high- and low-side outp...
