BA6428F-E2

Overview

The BA6428F-E2 is a single-phase full-wave fan motor driver manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3V to 14V and features an 8-SOP package. The device draws a typical operating supply current of 9 mA and functions reliably across a temperature range of -40°C to +85°C. Designed for SMD/SMT installation, this integrated circuit serves as a dedicated controller for small fan motors.

Feature Summary

• Integrated single-phase full-wave drive capability for fan motors
• Compact surface-mount 8-SOP packaging for space-constrained designs
• Wide operational voltage tolerance supporting 3V to 14V systems

Applications

• Single-phase brushless DC fan motor control
• Small appliance cooling systems
• HVAC unit fan drivers

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment against the official datasheet specifications. Ensure storage conditions meet semiconductor handling standards to prevent moisture damage prior to reflow soldering processes.

Selection Notes

Evaluate thermal dissipation requirements given the SOP-8 form factor. Verify that the load current remains within safe operating limits for the specific application. Consider availability constraints as the part is marked obsolete or not recommended for new designs in some regions.

Part Context

This component belongs to ROHM's motor driver portfolio, specifically targeting low-power fan applications. It integrates necessary drive logic into a compact footprint, reducing external component count compared to discrete solutions. The series focuses on reliability for continuous operation in consumer electronics.

Replacement Considerations

Check for direct cross-references from ROHM or compatible third-party equivalents. Verify pin compatibility and electrical parameters before substitution. Consult manufacturer obsolescence notices for long-term supply chain planning.
