DATA SHEET

MOS INTEGRATED CIRCUIT

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.

FEATURES

•

High drive current

≤ 200 ms, duty cycle ≤ 50%
