ROHM BD6370GUL, BD6758MWV, BD6758KN Technical data
System Lens Driver for Digital Still Cameras / Single-lens Reflex Cameras
5ch System Lens Drivers
for Digital Still Cameras
BD6370GUL, BD6758MWV, BD6758KN
No.09014EAT01
●Description
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-ON Drive 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 unit depending on the application.
