BD6889GU - 7-Channel System Lens Driver

Description

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.

Features
