MONOLITHIC H BRIDGE DRIVER
DESCRIPTION
This IC is a monolithic H bridge driver employing a horizontal N-channel power MOS FET for its driver stage.
It is provided with forward/reverse and brake functions and is ideal as a driver circuit for a motor that winds or
rewinds the film in a camera, or a motor for moving a lens.
