BM62300MUV-E2

Overview

The BM62300MUV-E2 is a brushless DC motor driver IC designed for fan and pump applications. It integrates a high-side P-channel MOSFET bridge, gate drivers, and protection circuits. Key electrical parameters include a supply voltage range of 4.5V to 18V and a continuous output current capability of up to 1.5A per phase. The device supports PWM speed control via an external input signal. It features built-in overcurrent protection, thermal shutdown, and under-voltage lockout mechanisms to ensure reliable operation in demanding environments.

Feature Summary

• Integrates high-side P-channel MOSFETs for simplified external component requirements
• Includes comprehensive protection functions such as overcurrent detection and thermal shutdown
• Supports analog or PWM-based speed control inputs for flexible system integration

Applications

• Computer cooling fans
• Server and storage drive cooling systems
• HVAC unit blowers
• Small household appliance motors

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pin compatibility and RoHS status. Ensure the operating temperature range aligns with your system's thermal design. Cross-reference the package type MUV (USPQFN) dimensions with your PCB footprint library to prevent assembly errors during procurement.

Selection Notes

Select this component when a compact solution for driving small BLDC motors is required without external power transistors. Consider the 1.5A current limit when sizing for load requirements. Evaluate the need for integrated protections versus discrete solutions based on board space constraints and reliability targets for the specific application environment.

Part Context

This part belongs to Rohm's series of integrated motor drivers aimed at reducing bill-of-materials count. It replaces discrete MOSFET and driver combinations by consolidating power switching and control logic into a single QFN package. This integration helps minimize electromagnetic interference and simplifies layout for high-density electronic designs.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as variants with different suffixes indicating updated revisions or packaging options. Verify that any substitute maintains the same voltage rating and current capacity. Consult official substitution guides from Rohm Semiconductor for validated alternatives.
