Product details

BU64982GWZ-TR: Uni-Directional VCM Driver for Autofocus – 6-XFBGA (CSPBGA)
The BU64982GWZ-TR from Rohm Semiconductor is a compact uni-directional voice coil motor (VCM) driver optimized for autofocus camera modules. Featuring I²C control, constant current drive architecture and an ultra-small 6-XFBGA package, it enables accurate lens positioning in space-constrained mobile imaging systems.

Product Introduction

The BU64982GWZ-TR is a high-efficiency CMOS-based VCM driver developed by Rohm Semiconductor for autofocus applications in smartphones, tablets and compact imaging devices.

Designed to drive voice coil motors with precise constant-current control, the device ensures smooth lens motion and stable focus acquisition. Its integrated control circuitry reduces external component count and simplifies camera module design.

The device is packaged in a miniature 6-XFBGA (CSPBGA), making it suitable for high-density PCB layouts in thin mobile devices.

Key Benefits
