TDA7391PD13TR

Overview

The TDA7391PD13TR is a single-channel Class AB bridge audio power amplifier designed for automotive applications. It operates on a single supply voltage ranging from 6V to 18V. The device delivers up to 45W of output power into a 3.2-ohm load. Key electrical specifications include a gain bandwidth product of 75kHz, an input bias current of 10uA, and a maximum operating temperature of +150°C. It features differential inputs and supports through-hole or surface-mount installation in PowerSO-20 packaging.

Feature Summary

• Integrated protection mechanisms including thermal shutdown and short-circuit protection
• Supports differential input configuration for improved noise immunity
• Includes pop-noise elimination and standby mode functionality

Applications

• Automotive radio high-power applications
• Car audio systems requiring robust Class AB amplification
• Single-channel mono audio output stages

Procurement Notes

Verify the specific suffix 'PD13TR' to confirm the PowerSO-20 surface-mount package and tape-and-reel delivery format. Ensure compatibility with the 6V to 18V single-supply requirement. Confirm that the AEC-Q100 qualification meets your automotive reliability standards. Cross-reference the manufacturer part number against official STMicroelectronics documentation to avoid confusion with similar variants like the TDA7391P.

Selection Notes

Select this component when a single-channel, high-power Class AB solution is required for automotive environments. It is suitable for designs needing differential inputs and integrated thermal protection. Consider the PowerSO-20 package constraints for PCB layout. Verify that the 45W output capability aligns with the speaker impedance and supply voltage limits of the target application.

Part Context

This component belongs to the TDA7391 series of automotive audio amplifiers by STMicroelectronics. The series is characterized by high power capability and robustness for car radio applications. The PD13TR variant specifically denotes the surface-mount PowerSO-20 package with tape-and-reel packaging, distinguishing it from through-hole versions.

Replacement Considerations

Check for direct substitutes within the TDA7391 family, such as TDA7391PDUTR, ensuring package and pinout compatibility. Verify if alternative STMicroelectronics automotive amplifiers meet the same 45W power and Class AB performance requirements.
