Motor Drivers for Digital Still Cameras
6-Channel System Lens Driver
for Digital Still Cameras
BD6373GW
General Description
The BD6373GW is a motor driver that integrates 6
Full-ON type H-Bridges. The device is intended to
drive a stepping motor for auto focus system, and
another stepping motor for either zoom or iris. It can
also be used to drive an actuator of the new system
like a lens barrier.
