TDA7391LVPDU

Overview

The TDA7391LVPDU is a bridge class AB audio power amplifier designed for car radio applications. It delivers high power capability with differential or single-ended input modes, suitable for high-end equipment. The device features an exclusive fully complementary output stage and internal fixed gain to minimize external components. It includes on-board clipping detection for gain compression implementation. The amplifier supports low voltage operation compatible with 'start-stop' battery profiles and e-call functions.

Feature Summary

Supports both differential and single-ended input signal configurations
Includes on-board clipping detector for easy gain compression system implementation
Compatible with low voltage 'start-stop' battery profiles and e-call functions
Features comprehensive protection against short circuits, thermal overload, and load dump

Applications

High-end car radio equipment
Automotive audio systems requiring low voltage operation
Vehicles equipped with start-stop technology
Systems supporting e-call functionality

Procurement Notes

Verify the specific suffix LVPDU against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with automotive environmental standards and voltage requirements before integration. Confirm current availability status as product lifecycle changes may affect supply continuity.

Selection Notes

Select this component for designs requiring a robust Class AB amplifier with differential input flexibility. It is appropriate for applications needing integrated protections and low-voltage compatibility without extensive external circuitry. Consider the Multiwatt-11 package constraints for thermal management in enclosed automotive environments.

Part Context

The TDA7391LVPDU belongs to the TDA7391LV series of bridge car radio amplifiers. This series is characterized by low voltage operation capabilities and high power output. It serves as a specialized solution for modern automotive audio systems that demand reliability under varying battery conditions.

Replacement Considerations

Check for direct pin-compatible alternatives within the TDA7391 family. Verify if newer generations offer improved efficiency or additional diagnostic features while maintaining the same form factor and electrical specifications.
