BU6906NUX-TR

Overview

The BU6906NUX-TR is a single-phase full-wave fan motor driver manufactured by ROHM Semiconductor. Designed for surface mount applications in VSON-8 packages, it operates within an ambient temperature range of -40°C to +85°C. The device supports a supply voltage range from 1.8V to 7V maximum, delivering up to 800mA output current with a typical operating supply current of 10mA. It features a 7V output voltage capability and dissipates up to 410mW of power.

Feature Summary

• Integrated single-phase full-wave driver topology optimized for fan motor control
• Compact VSON-8 surface-mount package design for space-constrained PCB layouts
• Operational stability across extended industrial temperature ranges

Applications

• Computer cooling fan systems
• Server chassis ventilation units
• Consumer appliance motor control circuits

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official datasheets. Check for End-of-Life notifications as discontinuance may affect long-term availability. Validate package markings against manufacturer specifications to prevent counterfeit infiltration during sourcing.

Selection Notes

Evaluate thermal dissipation requirements against the 410mW power rating. Ensure supply voltage compatibility with the 1.8V to 7V operational window. Consider the 800mA current limit when sizing load connections. Verify that the VSON-8 footprint aligns with existing board design constraints and assembly capabilities.

Part Context

This component belongs to ROHM's PMIC Motor Driver category, specifically targeting brushless DC and fan motor applications. It falls under the broader class of motion controllers designed for low-power, high-efficiency switching operations in consumer and industrial electronics environments.
