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.
Applications
VCR cylinder motors
Features
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.
