- Car audio center units
Procurement Notes
Verify the current lifecycle status before procurement as this component may be marked as Not Recommended for New Designs. Confirm that the HTSSOP-B-54 package dimensions align with your PCB footprint requirements. Ensure your design accommodates the specified thermal dissipation characteristics for the operating temperature range. Validate compatibility with the required 10 V to 26 V supply rails and digital input logic levels.
Selection Notes
Select this component when a high-efficiency stereo solution is required for automotive environments. It is suitable for designs needing 40 W total output into 5.4 Ohm loads. Consider the digital input requirement if interfacing directly with DSPs or microcontrollers. The wide supply voltage range allows flexibility in system power architecture. Verify that the thermal performance meets the enclosure constraints for the -25°C to +85°C operational window.
Part Context
This part belongs to the BD54 series of audio amplifiers from ROHM Semiconductor. The series focuses on Class-D technology optimized for automotive applications. The BD5446EFV-E2 variant specifically addresses stereo channel requirements with higher power output capabilities compared to mono variants in the same family.
Replacement Considerations
Check for updated ROHM datasheets for potential end-of-life notices. Evaluate other BD54 series members for pin-compatible alternatives if availability is constrained.
