System Lens Drivers

μ

-step System Lens Driver

for Digital Still Cameras

BU24036MWV

●

General Description

BU24036MWV 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

moor and voice coil motor and a μ-step controller that

decreases CPU power. Therefore, multifunctional lens

can be applied.
