for Digital Still Cameras

BD6889GU

General Description

Key Specifications

The BD6889GU is a motor driver that integrates 6

Full-ON type H-Bridges and 1 Linear Constant-Current

type H-Bridge. The device is intended to drive three

stepping motor for auto focus system, zoom, and iris,

and making it possible to design a sophisticated, high

precision lens drive system.
