Product details
Product Introduction
BU64243GWZ-TR is a ROHM VCM lens driver designed for autofocus in mobile camera modules. It provides stable current control to move the lens smoothly and repeatably, supporting autofocus algorithms that require fine step positioning.
The device includes ISRC to reduce mechanical ringing, improving settling time after lens motion. With 10-bit current control and a 2-wire serial interface, it integrates well into camera module control buses.
An integrated current sense resistor helps reduce BOM and improves consistency across builds. Supply range is commonly listed as 2.3V–4.8V for typical mobile rails.
Key Benefits
Constant current drive supports smooth lens movement.
ISRC reduces oscillation after step movements.
10-bit resolution improves repeatability and tuning flexibility.
Designed for space-constrained camera modules.
Technical Features
Suitable for VCM actuator drive topology in compact modules.
Simple interface for ISP/SoC integration in camera stacks.
Reduces external components and helps production consistency.
