STA50513TR

Overview

The STA50513TR is a monolithic quad half-bridge audio amplifier stage manufactured by STMicroelectronics using Multipower BCD technology. It supports 40V operation and delivers up to 3.5A output current per channel. The device functions as a Class D power amplifier, configurable for either one-channel mono or two-channel stereo applications. Key electrical characteristics include a maximum operating temperature of 90°C and an output power rating of 80W. It is housed in a PowerSO-36 surface-mount package.

Feature Summary

• Monolithic quad half-bridge architecture utilizing Multipower BCD technology
• Configurable for mono or stereo audio output channels
• Integrated thermal shutdown protection
• Designed for minimum input-to-output pulse width distortion

Applications

• High-fidelity audio amplification systems
• Multi-channel speaker driver circuits
• Consumer electronics requiring robust power stages

Procurement Notes

Verify the specific datasheet revision and ordering suffix to ensure compatibility with your design requirements. Confirm that the PowerSO-36 package dimensions match your PCB footprint. Check for RoHS compliance status if required by your manufacturing standards. Ensure supply chain authenticity through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a high-current, multi-channel bridge configuration is needed within a single IC. Consider the 40V voltage rating and 3.5A current capability against load impedance requirements. Evaluate the thermal management needs given the 90°C max operating temperature and 80W power output potential. Compare package size constraints against available board space for the PowerSO-36 form factor.

Part Context

This part belongs to the STA505 series of audio amplifiers from STMicroelectronics. The series utilizes Multipower BCD technology to integrate high-voltage and low-voltage processes on a single chip. This integration allows for compact designs with reduced external component count compared to discrete solutions.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify equivalent voltage, current, and package specifications before substitution. Cross-reference technical parameters such as distortion levels and thermal characteristics to ensure functional parity.
