for Digital Still Cameras
BD6753KV
General Description
The BD6753KV is a motor driver that integrates 4
Full-ON type H-Bridges and 2 PWM Constant-Current
type H-bridges. The device is intended to drive two
stepping motors for auto focus system, either zoom or
iris. It is also available for the new system like a lens
barrier.
