BD6758MWV Datasheet

5ch System Lens Drivers for Digital Still Cameras


The BD6370GUL motor driver provides 3 Constant-Voltage Drive / Full-ON Drive H-bridge channels, 1 Constant-Voltage Drive / Linear Constant-Current Drive / Full-ON Drive H-bridge channel, and 1 Constant-Current Drive H-bridge channel, while the BD6758MWV and the BD6758KN provides 4 Full-ONDrive H-bridge channels and 1 Linear Constant-Current Drive H-bridge channel.
A Stepping motor can be used for auto focus and a DC motor for zoom and iris. ROHM offers both an advance type equipped with a D/A converter in all channels and a standard type, allowing selection of the ideal unitdepending on the application.
