BD62018AFS-E2

Overview

The BD62018AFS-E2 is a three-phase brushless fan motor controller manufactured by ROHM Semiconductor. It operates within a supply voltage range of 10 V to 18 V, with a maximum rating of 18 V. The device supports an output current of 15 mA and draws a typical operating supply current of 2.5 mA. It functions reliably across an extended temperature range from -40 °C to +110 °C. The component is housed in a compact SSOP-A-24 surface-mount package, designed for efficient integration into space-constrained electronic assemblies requiring precise fan speed control.

Feature Summary

• Integrated three-phase drive architecture specifically optimized for brushless DC fan motors
• Built-in protection mechanisms to ensure operational stability under varying load conditions
• Compact surface-mount packaging facilitates automated assembly and reduced board footprint

Applications

• Computer cooling fan systems
• Server chassis ventilation controllers
• Consumer electronics thermal management units

Procurement Notes

Verify the specific suffix E2 against the official ROHM datasheet to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm availability status, as components may be subject to lifecycle changes or discontinuation notices without prior announcement.

Selection Notes

Select this component when designing systems requiring dedicated three-phase control for small brushless fans. The 15 mA output capability suits low-power applications where higher current drivers are unnecessary. Consider the SSOP-A-24 package dimensions during PCB layout planning. Verify that the 10 V minimum supply voltage aligns with your system's power rail specifications before finalizing the design.

Part Context

This part belongs to the BD62018 series of motor controllers from ROHM Semiconductor. It is engineered for high-efficiency operation in consumer and industrial cooling applications. The series emphasizes reliability and thermal performance within a small form factor. Related variants may offer different current ratings or package options, but this specific model targets the 15 mA output niche for standard fan modules.

Replacement Considerations

The BD62018BFS-E2 is a documented alternative within the same product family. Both parts share similar three-phase control functionality and package types. Verify pin compatibility and electrical parameter alignment before substitution. Consult the official replacement guide for any functional differences between the AFS and BFS suffixes.
