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
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.
4) Constant supply voltage pin for hall devices.
5) High ratio of output current and control current.
(4000 typically)
6) Available in a compact surface-mount package.
