Parallel Interface Type
Lens Drivers for Stepping Motor
BD6360GUL
●Description
The BD6360GUL motor driver provides 2 Full-ON Drive H-bridge channel.
It is offered in an ultra small functional lens system for use in an auto focus or zoom system using a stepping motor.
And It integrates a power supply and wave-shaping circuit for the photo-interrupter necessary in order to determine the
location of the motor.
●Features
