BD6671FM-E2

Overview

The BD6671FM-E2 is a spindle motor driver manufactured by ROHM Semiconductor, designed for optical disc drive applications. It operates within a supply voltage range of 4.5V to 5.5V and features a half-bridge output configuration with an output current capacity of 2.5A. The component is housed in a 28-HSOP-M package, which measures 0.295 inches (7.50mm) in width and includes two thermal pads for heat dissipation. It supports surface-mount installation and functions across a temperature range of -40°C to 85°C. The device draws a supply current of 22.9mA and is classified as RoHS3 compliant.

Feature Summary

Integrated half-bridge power MOSFET technology for efficient spindle motor control
Built-in thermal pad design on the 28-HSOP-M package to enhance heat dissipation
Optimized for low-voltage operation suitable for portable optical drive systems

Applications

CD-ROM drive spindle motor control
DVD drive spindle motor drivers
Portable optical storage devices

Procurement Notes

Verify the specific suffix E2 against the official ROHM datasheet to confirm package and material specifications. Check the lifecycle status, as this part may be marked obsolete or end-of-life. Ensure compatibility with existing PCB footprints for the 28-HSOP-M package. Confirm RoHS3 compliance requirements for your manufacturing process. Validate that the 2.5A output current meets the load requirements of the target spindle motor.

Selection Notes

Select this component when designing CD or DVD drive systems requiring a dedicated single-phase spindle motor driver. The 2.5A output current rating suits standard optical drive motors. The 28-HSOP-M package is appropriate for space-constrained board layouts. Consider the 4.5V to 5.5V operating range for system power supply design. Evaluate thermal management needs due to the integrated MOSFET structure.

Part Context

This part belongs to ROHM's family of motor controllers and drivers specifically tailored for motion control in consumer electronics. The BD6671 series focuses on spindle applications for optical media players. The FM suffix typically indicates a specific package variant within the product line. These components are engineered for reliability in high-volume consumer hardware manufacturing.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if the BD6671FM without the E2 suffix is functionally equivalent. Consult ROHM engineering for direct replacements if this part is obsolete.
