Product details
Product Introduction
BU64244GWZ-TR is a ROHM lens driver IC built for driving voice coil motors (VCM) in mobile camera autofocus modules. It provides stable current drive for smooth lens motion and accurate positioning.
The device integrates ISRC (Intelligent Slew Rate Control) to reduce mechanical ringing, helping autofocus settle faster after movement and improving focus stability in real usage.
With 2.3V–4.8V operating range and an ultra-small UCSP35L1 package, BU64244GWZ-TR supports compact camera module layouts and reduced BOM designs via integrated current sensing.
Key Benefits
ISRC reduces ringing for quicker stabilization after lens steps.
10-bit resolution supports smooth positioning and repeatability.
UCSP package helps shrink autofocus actuator designs.
Integrated current sense resistor reduces external components.
Technical Features
Current sink architecture designed for VCM actuation.
Simple control interface for camera ISP/SoC designs.
Improves current-control consistency across production.
