TDA7384B

Overview

The TDA7384B is a Class-AB audio power amplifier manufactured by STMicroelectronics, designed for automotive applications. It features four channels delivering 42W per channel into a 4-ohm load. The device operates on a single supply voltage ranging from 8V to 18V. It utilizes a 25-Flexiwatt package with formed leads for through-hole mounting.

Feature Summary

• Four-channel quad bridge output configuration
• Integrated mute, standby, and thermal protection functions
• Short-circuit protection capabilities

Applications

• Automotive radio systems
• Car audio amplification
• Vehicle sound system integration

Procurement Notes

Verify the specific suffix 'B' against official STMicroelectronics documentation to confirm package orientation and pinout compatibility. Confirm current production status as listings indicate this variant may be discontinued compared to the active TDA7384A version. Ensure the selected component matches the required Flexiwatt form factor for the target PCB design.

Selection Notes

Select this component for high-power multi-channel automotive audio requirements where robust protection features are essential. Compare against the TDA7384A to determine if package orientation differences impact mechanical assembly. Verify that the 8V to 18V operating range aligns with the vehicle's electrical system specifications.

Part Context

This part belongs to the TDA738x series of automotive audio amplifiers. It shares functional similarities with the TDA7384A but differs in physical package characteristics. The series is engineered for reliability in harsh automotive environments, offering high output power within a compact footprint suitable for space-constrained vehicle installations.

Replacement Considerations

The TDA7384A is a verified substitute part number within the same family. Verify package orientation compatibility before substitution.
