Overview
The BU6904NUX-GTR is a single-phase full-wave fan motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of up to 5.5 V and delivers an output current of 800 mA. The device features a low operating supply current of 2 mA and functions reliably across a temperature range from -40 °C to +85 °C. It is housed in an 8-pin VSON package designed for surface mount technology.
Feature Summary
- Designed specifically for driving single-phase full-wave fan motors
- Integrates high-current output stage capable of 800 mA drive capability
- Optimized for low power consumption with minimal quiescent current draw
Applications
- Single-phase AC fan motor control systems
- Full-wave rectified fan motor drive circuits
- Low-power ventilation equipment motor drivers
Procurement Notes
Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity and pin alignment against the VSON-8 specification before integration. Ensure design compatibility with existing single-phase full-wave topologies given the discontinued lifecycle status.
Selection Notes
Select this component for applications requiring dedicated single-phase full-wave fan motor control. Evaluate thermal performance within the specified -40 °C to +85 °C range. Consider the 800 mA output limit when sizing for specific fan loads. Verify supply voltage constraints do not exceed the 5.5 V maximum rating during operation.
Part Context
This component belongs to ROHM's portfolio of fan and motor controllers/drivers. It serves as a specialized integrated circuit for managing single-phase motor operations. The product line focuses on compact, efficient solutions for small appliance and ventilation motor control applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed with an obsolete lifecycle status. Designers should consult official manufacturer discontinuation notices or technical support for validated alternative recommendations.
