BD5465GUL-E2

Overview

The BD5465GUL-E2 is a monaural Class-D speaker amplifier manufactured by ROHM Semiconductor, designed for analog input audio applications. It delivers an output power of 600 mW with a total harmonic distortion plus noise (THD+N) of 0.2%. The device operates within a supply voltage range of 2.5 V to 5.5 V and draws a working power supply current of 3.3 mA. It features a fixed gain of 12 dB and includes a shutdown function for power management. The component is housed in a compact 9-VCSP package (9-VCSP50L1, 1.8x1.8 mm) suitable for surface mount installation. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Class-D amplification architecture enables high efficiency and low power consumption for battery-driven portable devices.
• Integrated automatic pop-noise reduction circuit minimizes audible transients during startup and shutdown transitions.
• Built-in protection mechanisms include thermal shutdown and short-circuit protection to ensure operational reliability.

Applications

• Mobile phone audio systems
• Portable electronic devices requiring low-voltage operation
• Monaural speaker driver circuits in consumer electronics

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm compliance with RoHS directives and material declarations. Confirm that the 9-VCSP50L1 package dimensions match the target PCB footprint requirements. Ensure the analog input interface aligns with the source signal characteristics before integration into the design.

Selection Notes

Select this component when a single-channel audio solution is required with minimal external passive components. The fixed 12 dB gain suits applications where signal conditioning is handled upstream. Consider the 600 mW output capability relative to the connected speaker impedance and desired volume levels within the constrained 2.5 V to 5.5 V supply window.

Part Context

This part belongs to the BD546xGUL series of wafer-level CSP packaged low-voltage monaural Class-D speaker amplifiers developed by ROHM Semiconductor. The series targets mobile phones and portable electric devices, offering various gain configurations and control options within a unified small form factor platform.

Replacement Considerations

The BD5465GUL is listed as an alias for this part number. Verify pinout compatibility if substituting with other members of the BD546xGUL family, such as the BD5466GUL or BD5467GUL, which may differ in gain settings or ALC features.
