Overview
The BD6961F-E2 is a single-phase full-wave DC brushless fan motor driver manufactured by ROHM Semiconductor. It integrates power MOSFETs and control circuitry in an 8-pin SOP package. The device operates within a supply voltage range of 3.3V to 14V. It supports PWM current drive for speed control and enables silent operation modes. The component is designed for low-consumption applications, featuring integrated protection mechanisms suitable for direct integration into fan motor systems.
Feature Summary
- Integrates power MOSFETs and control logic in a compact SOP-8 package
- Supports external PWM signal input for adjustable speed control
- Enables silent driving operation to minimize acoustic noise
- Designed for low-power consumption in single-phase BLDC fan applications
Applications
- DC brushless fan motor drives
- Single-phase BLDC cooling systems
- Low-power ventilation units
Procurement Notes
Verify the specific suffix 'E2' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the operating voltage requirements align with the 3.3V to 14V range specified in the datasheet. Confirm thermal management capabilities match the SOP-8 package limitations for the intended application load.
Selection Notes
Select this component for single-phase BLDC fan applications requiring integrated power stages. Consider the 3.3V to 14V input range for system compatibility. Evaluate the need for PWM speed control and silent operation features. Verify that the SOP-8 footprint fits the PCB layout constraints compared to alternative packages like HSOP or HTSSOP.
Part Context
This part belongs to ROHM's series of motor drivers and controllers designed for fan applications. It complements other ROHM products such as the BD60210fv for brushed motors and the BD68960ekv-c for stepper motors. The family focuses on integrating control and power levels to simplify design for consumer electronics and industrial ventilation.
