• Integrated microstepping control for precise lens positioning
• Supports bipolar brushed DC and voice coil motor types
• Optimized for low-voltage digital camera systems

Applications

• Digital camera lens actuation
• Voice coil motor control in imaging devices
• Bipolar brushed DC motor drivers in compact electronics

Procurement Notes

Verify the exact suffix E2 matches the required RoHS compliance and tape/reel packaging specifications. Confirm the 75-pin UCSP footprint compatibility with your PCB layout before ordering. Ensure the 2.7-3.6V supply rail aligns with your system design constraints.

Selection Notes

Select this component when precise microstepping is required for lens mechanisms in portable devices. It is suitable for designs constrained by low voltage operation and small form factor requirements. Consider thermal dissipation capabilities within the UCSP package for high-duty-cycle applications.

Part Context

This part belongs to ROHM's BU2403x series of lens drivers, specifically engineered for mobile phone cameras and compact digital imaging equipment. The series offers integrated solutions for motor control, reducing external component count compared to discrete driver designs.

Replacement Considerations

Check ROHM datasheets for direct pin-compatible alternatives within the BU2403x family. Verify electrical parameters such as output current and operating voltage against the original design requirements before substituting.
