Overview
The BD67173NUX-E2 is a three-phase full-wave fan motor driver designed for brushless DC motors. It operates on a power supply voltage range of 2.2 V to 5.5 V, with a maximum output current of 700 mA and a quiescent current of 4.2 mA. The device supports PWM speed control and features a soft-switched drive mechanism for silent operation. It is housed in a compact 10-pin VSON package (3.0x3.0 mm) and functions within an operating temperature range of -25°C to +95°C.
Feature Summary
- Sensorless drive capability eliminating the need for Hall effect sensors
- Direct PWM soft-switched driving mechanism for low noise and vibration
- Integrated quick start function for rapid motor initialization
- Power save mode to reduce operational current consumption
Applications
- Notebook PC cooling fans
- Portable electronic device thermal management
- Small form-factor fan motor systems
Procurement Notes
Verify the specific suffix E2 against the official ROHM datasheet to confirm compliance with RoHS directives and material declarations. Ensure the ordering part number matches the required tape-and-reel quantity of 4000 units or cut-tape availability. Confirm that the VSON-10 footprint aligns with the target PCB layout specifications before finalizing procurement orders.
Selection Notes
Select this component when designing sensorless BLDC motor drivers for notebook PCs requiring silent operation. The integrated soft-switching technology minimizes acoustic noise compared to hard-switched alternatives. Consider the 2.2V to 5.5V input range compatibility with standard logic levels and battery-powered systems. The compact VSON package suits space-constrained mobile applications.
Part Context
This IC belongs to ROHM's series of three-phase brushless DC motor controllers specifically optimized for fan applications. It utilizes a sensorless commutation algorithm to detect rotor position, reducing external component count. The product line emphasizes miniaturization and energy efficiency for portable computing devices.
Replacement Considerations
The BD67173NUX is listed as an alias for this part number. Verify pinout and electrical characteristics against the latest datasheet revision before substituting.
