Overview
The BD6982FVM-GTR is a single-phase fan motor driver IC manufactured by ROHM Semiconductor. It operates within a supply voltage range of 2.8V to 16V and delivers an output current capability of up to 0.8A. The device features a BTL (Bridge-Tied Load) soft switching architecture designed for quiet motor operation. Key electrical specifications include a maximum power dissipation of 580mW and an output voltage drop of approximately 450mV. It supports 5V and 12V power supplies and functions reliably across an operating temperature range from -40°C to +105°C.
Feature Summary
- Integrates BTL soft switching technology to minimize acoustic noise during fan motor operation
- Includes capacitor lock protection functionality to prevent damage under fault conditions
- Supports single-phase full-wave drive configurations for efficient motor control
Applications
- Automotive in-vehicle infotainment system cooling fans
- Automotive seat ventilation fan motors
- LED headlight assembly cooling systems
Procurement Notes
Verify the specific suffix GTR indicates tape-and-reel packaging when sourcing. Confirm AEC-Q100 automotive grade qualification status if required for your application. Ensure the MSOP-8 package dimensions match your PCB footprint requirements. Check for end-of-life or not-recommended-for-new-designations on distributor platforms before finalizing procurement plans.
Selection Notes
Select this component for applications requiring low-noise single-phase fan control with integrated protection. The BTL configuration eliminates external components typically needed for bridge drivers. Consider the 0.8A output limit against peak motor startup currents. The wide operating temperature range suits harsh automotive environments without additional thermal management.
Part Context
This part belongs to ROHM's automotive-grade motor driver portfolio, specifically designed for cooling fans in vehicle systems. It complements other models like the BD6985FVM-M within the same family. The MSOP-8 package provides a compact solution for space-constrained automotive electronics while maintaining robust performance standards.
Replacement Considerations
The BD6985FVM-M serves as a functional substitute within the same product family. Verify pin compatibility and output current ratings between these variants. Both devices share similar automotive qualification standards and package types.
