Overview
The BD6971FS-E2 is a fully integrated brushless DC motor driver manufactured by ROHM Semiconductor. It combines control and power stages using N-channel middle power MOSFET technology. The device supports PWM interfaces and operates within a supply voltage range of 3.5 V to 17 V, with a maximum load voltage of 17 V. It delivers an output current of 1 A through two half-bridge outputs. The component functions reliably across a junction temperature range of -40°C to +150°C. It is housed in a 16-SSOP-A package and consumes a typical operating supply current of 5 mA.
Feature Summary
- Fully integrated design combining control logic and power stage
- Supports PWM interface for precise motor control
- Utilizes N-channel middle power MOSFET technology
Applications
- Fan motor drivers
- Brushless DC (BLDC) motor applications
Procurement Notes
Verify the current lifecycle status before integration, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the 16-SSOP-A package dimensions align with existing PCB footprints. Ensure thermal management strategies account for the specified power dissipation limits under expected load conditions. Validate compatibility with the target system's PWM signal levels and voltage requirements.
Selection Notes
Select this component for applications requiring a compact, single-chip solution for BLDC fan motors. The integrated nature reduces external component count compared to discrete driver solutions. Consider the wide operating temperature range for environments with significant thermal fluctuations. Verify that the 1 A output current capability meets the specific motor load requirements without exceeding safe operating areas.
Part Context
This part belongs to the BD6971 family of motor controllers from ROHM Semiconductor. It is categorized under PMIC Motor Drivers and Controllers. The device is designed specifically for driving small to medium-sized brushless DC motors commonly found in cooling systems. It represents a specialized solution for integrating motor drive functionality into space-constrained electronic designs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official manufacturer resources for potential end-of-life alternatives or pin-compatible upgrades if this component is discontinued.
