●Description
BD6757KN and BD6889GU motor drivers provide 6 Full-ON Drive H-bridge channels and 1 Linear Constant-Current Drive H-bridge channel. Stepping motors can be used for the auto focus, zoom, and iris, making it possible to configure a sophisticated, high precision lens drive system. ROHM’s motor drivers are both compact, multifunctional, and enable advanced features such as lens barrier and anti shock.
