BD5413EFV-E2

Overview

The BD5413EFV-E2 is a stereo Class-D speaker amplifier manufactured by ROHM Semiconductor, designed for analog input applications. It delivers 5 W per channel into an 8 Ω load, with a maximum output of 4 W + 4 W under specific conditions. The device operates on a single power supply ranging from 6 V to 10.5 V and features a gain of 30 dB. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.2%. It utilizes an HTSSOP-B-24 package with SMD/SMT mounting style and supports a shutdown function. The operational temperature range spans from -40 °C to +85 °C, with a typical operating supply current of 12 mA.

Feature Summary

• High efficiency achieved through advanced BCD process technology, minimizing internal losses in the output stage.
• Compact back-side heat dissipation package design eliminates the need for external heat sinks.
• Integrated shutdown function for effective power management and standby current reduction.

Applications

• Low-power audio systems requiring minimal heat generation
• Portable electronic devices demanding small form factor amplifiers
• Audio equipment prioritizing high sound quality with reduced thermal footprint

Procurement Notes

Verify component authenticity against official ROHM Semiconductor documentation before integration. Confirm that the HTSSOP-B-24 package dimensions and pinout match your PCB layout requirements. Ensure thermal management strategies align with the specified operating temperature range of -40 °C to +85 °C. Check for moisture sensitivity levels if storage or reflow soldering processes are involved. Validate that the analog input signal levels are compatible with the 30 dB fixed gain configuration.

Selection Notes

Select this component when a compact, high-efficiency Class-D amplifier is required for analog audio sources. It is suitable for designs where space constraints prevent the use of external heatsinks. Consider the 6 V to 10.5 V supply voltage range to ensure compatibility with your system's power architecture. The 30 dB gain setting should be evaluated against your input signal amplitude to avoid clipping or insufficient volume.

Part Context

This part belongs to the BD54 series of audio power amplifiers from ROHM Semiconductor. The series focuses on integrating high-output power stages with control logic in a single IC to reduce system size. The BD5413EFV-E2 specifically targets stereo applications, offering a balance between performance and thermal efficiency compared to traditional linear amplifiers.

Replacement Considerations

The BD5413EFV is listed as an alias for this component. Verify pin-to-pin compatibility and electrical specifications if considering alternative Class-D amplifiers from other manufacturers. Ensure any substitute matches the HTSSOP-B-24 package and 30 dB gain requirement.
