Linear/PWM Constant Current VCM Driver - BU64291GWZ (New)

The BU64291GWZ is designed to drive voice coil motors (VCM) and operate with PWM to improve system power efficiency or switch to linear control to improve system noise. The driver includes ISRC (intelligent slew rate control) to reduce mechanical ringing to optimize the camera’s auto focus capabilities.
