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 ampli-
fier control circuit, driver circuits, FG / PG signal amplifiers, and hysteresis amplifiers.
FApplications
VCR cylinder motors
