Overview
The TDA7566 is a quad bridge class AB audio amplifier designed for automotive radio applications. It utilizes DMOS technology to deliver high output power with low distortion. The device operates within an 8V to 18V supply voltage range and provides up to 60W per channel into a 2-ohm load. It features full I2C bus control for configuration, diagnostics, and protection functions including short circuit, thermal, and DC offset detection.
Feature Summary
- Quad bridge architecture with DMOS output stage for high fidelity sound
- Full I2C bus interface for digital diagnostics and independent channel control
- Comprehensive protection suite including short circuit, thermal, and clipping detection
Applications
- Automotive radio systems
- In-vehicle infotainment audio amplification
- Car speaker driver circuits
Procurement Notes
Verify component status as the TDA7566 is listed as obsolete by STMicroelectronics. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing design constraints given the discontinuation notice dated March 31, 2023. Check for RoHS compliance and specific package variants if sourcing replacements.
Selection Notes
Select this component for applications requiring integrated diagnostics and I2C control in automotive environments. Consider the Flexiwatt25 package for thermal management. Evaluate power requirements against the 4x60W/2Ω capability. Verify that the system can support the required I2C communication protocol for gain selection and mute functions.
Part Context
The TDA7566 belongs to the TDA75xx series of car radio amplifiers from STMicroelectronics. It is part of the company's portfolio for smart driving and infotainment solutions. The device represents BCD technology integration for automotive audio applications, focusing on reliability and diagnostic capabilities within vehicle electrical systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the product is obsolete, engineers must evaluate alternative quad bridge amplifiers from the same manufacturer or competitors that meet the specific power, package, and I2C interface requirements.
