BU24038GW-E2

Overview

The BU24038GW-E2 is a system lens driver for digital cameras supporting micro-stepping. It integrates nine output channels: eight voltage-controlled H-bridges and one current-controlled H-bridge. The device operates within a supply voltage range of 2.7 V to 5.5 V, with a maximum power dissipation of 1.3 W. It functions at temperatures between -20°C and +85°C in a UCSP75M3-56 package.

Feature Summary

• Integrates nine driver channels including voltage-controlled and current-controlled H-bridges
• Supports micro-stepping control to reduce microcontroller processing load
• Includes built-in PI driving circuits and waveforming circuits
• Features an integrated PLL circuit for stable operation

Applications

• Digital camera lens drive systems
• High-precision optical zoom mechanisms
• Low-noise autofocus actuators

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm pinout compatibility and RoHS compliance status. Confirm that the UCSP75M3-56 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing camera modules requiring integrated micro-stepping capabilities without external logic. Ensure the application environment stays within the specified -20°C to +85°C operating temperature range. Verify that the 1.3 W power dissipation rating accommodates the thermal design of the host device.

Part Context

This part belongs to ROHM's series of motor and motion controllers designed specifically for imaging applications. It consolidates multiple discrete driver and control functions into a single compact surface-mount package, simplifying the bill of materials for consumer electronics manufacturers.

Replacement Considerations

BU24038GW is listed as an alias or predecessor variant. Verify electrical equivalence and package compatibility if substituting.
