Product details
Product Introduction
BU64295GWZ-TR is a ROHM autofocus VCM driver designed for accurate lens actuation using bi-directional constant-current control. Bi-direction capability supports flexible movement profiles, calibration offsets, and stable autofocus behavior across lens modules.
The driver includes ISRC mechanical ringing compensation to reduce oscillation in the VCM-lens system, improving settling time after movement. With 10-bit current control, small step adjustments are supported for smoother focus transitions.
Control is via a 2-wire serial interface (I²C compatible), and an integrated current sense resistor helps reduce external components and improve production consistency.
Key Benefits
Improves flexibility for AF algorithms and calibration.
ISRC helps reduce oscillation and improves stability.
10-bit resolution supports fine current stepping.
Integrated current sense resistor reduces external parts.
Technical Features
Supports forward/reverse current control for VCM actuation.
Simple integration into camera control buses.
Improves settling behavior after lens movement.
