Overview
The BD6326NUX-E2 is a three-phase full-wave fan motor driver manufactured by ROHM Semiconductor. It operates within a power supply voltage range of 2.2 V to 5.5 V, with a maximum output current of 700 mA and an operating supply current of 5.5 mA. The device supports PWM speed control inputs and functions at frequencies between 20 kHz and 50 kHz. It features four outputs and delivers an output voltage of 7 V, with a power dissipation rating of 580 mW. Designed for surface mount installation in a VSON-10 package (3.0x3.0 mm), it withstands temperatures from -25°C to +95°C.
Feature Summary
- Supports three-phase full-wave sinusoidal drive for brushless DC fan motors
- Integrates PWM speed control input functionality
- Utilizes power MOSFET logic technology for efficient driving
Applications
- Notebook PC cooling systems
- Fan motor drives in portable devices
- PDA thermal management
Procurement Notes
Verify the Not Recommended for New Designs (NRND) status before procurement, as this component is produced solely for existing customers. Confirm that the VSON-10 package dimensions match your PCB layout requirements. Ensure compatibility with the specified 2.2 V to 5.5 V supply range. Check RoHS compliance documentation if required by your manufacturing standards. Validate that the 700 mA output current meets your specific motor load demands.
Selection Notes
Select this component when a dedicated three-phase driver for small fan motors is required in space-constrained applications. The VSON-10 package offers a compact footprint suitable for mobile electronics. Consider the NRND status carefully; while suitable for maintenance or replacement designs, it is not intended for new product development. Evaluate the 580 mW power dissipation limit against your thermal environment to ensure reliable operation within the -25°C to +95°C temperature range.
Part Context
This part belongs to the BD6326NUX series of three-phase full-wave fan motor drivers. It is specifically engineered for driving brushless DC motors in notebook PCs and similar portable electronic devices. The series focuses on providing efficient motion control solutions with integrated PWM capabilities, targeting applications where size and power efficiency are critical constraints.
Replacement Considerations
The BD6326ANUX-E2 is documented as a substitute with the same package type. Both parts share identical physical dimensions and pinout configurations. Verify functional equivalence regarding electrical parameters before substitution, noting that the original part is no longer recommended for new designs.
