BU24020GU - System Lens Driver

Datasheet Summary

Description

BU24020GU 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.
