Motor driver ICs
2-phase motor driver for VCR cylinder motors
BA6970FS
The BA6970FS is a direct-drive motor driver suitable for 2-phase, full-wave linear motors.
The IC consists of a Hall amplifier control circuit, driver circuits, FG / PG signal
amplifiers, and hysteresis
amplifiers.
FApplications VCR cylinder motors FFeatures 1) Linear drive system provides low switching noise.
2) Output current can be controlled by either current or
voltage input.
3) Two
amplifiers and two hysteresis
amplifiers.
