μ-step System Lens Driver
for Digital Still Cameras
BU24024GU
●General Description BU24024GU is a system Lens Driver that uses μ-step driving to make the configuration of the sophisticated, high precision and low noise lens driver system possible.
This IC has a built-in driver for both DC motor and voice coil motor and a μ-step controller that decreases CPU power.
Therefore, multifunctional lens can be applied.
