Overview
The BD8256EFV-ME2 is a nine-channel motor driver designed for automotive audio-visual applications. It operates within a supply voltage range of 4.5 V to 10.5 V and supports a maximum operating frequency of 35 MHz. The device features a power dissipation rating of 2 W and functions reliably across an extended temperature range from -40°C to +90°C. Packaged in a compact HTSSOP-B54 format, it meets AEC-Q100 qualification standards for automotive reliability.
Feature Summary
- Nine independent output channels dedicated to automotive AV systems
- AEC-Q100 qualified for automotive environmental reliability
- Integrated protection mechanisms against thermal overload
Applications
- Automotive audio system fan control
- Vehicle ventilation blower motor regulation
- Car audio amplifier cooling management
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 HTSSOP-B54 package dimensions align with existing PCB footprints. Ensure the 4.5 V to 10.5 V input range matches the vehicle's electrical architecture. Check for moisture sensitivity classification requirements during assembly processing.
Selection Notes
Select this driver when nine distinct motor outputs are required for centralized AV control. It suits designs needing AEC-Q100 compliance without complex external logic. Consider the 2 W power dissipation limit for thermal management strategies. Evaluate the HTSSOP-B54 footprint constraints against available board space.
Part Context
This part belongs to ROHM’s portfolio of motor controllers tailored for automotive infotainment and climate systems. It integrates multiple drive channels into a single IC to reduce component count. The series emphasizes reliability under varying automotive electrical conditions.
Replacement Considerations
Check for direct pin-compatible alternatives if NRND status impacts long-term supply. Verify that substitute drivers maintain the same nine-channel configuration and voltage specifications.
