BD6889GU
General 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.
