TDA7560H

Overview

The TDA7560H is a Class-AB audio power amplifier designed for automotive applications, utilizing Multipower BCD technology. It features a fully complementary P-Channel/N-Channel output structure enabling rail-to-rail voltage swing. The device delivers up to 55W per channel into a 2Ω load at 14.4V with 10% THD+N, or 80W maximum per channel into 2Ω. It operates on a single supply voltage ranging from 8V to 18V, with a maximum single supply voltage of 28V. Key electrical parameters include a maximum quiescent current of 320mA at 13.2V and a maximum operating temperature of 150°C.

Feature Summary

• Integrated standby and mute functions with automute capability upon minimum supply voltage detection.
• Comprehensive protection mechanisms including output short-circuit to ground, to Vs, across the load, overtemperature soft limiter, and DC offset detection.
• Low external component count due to internally fixed gain and absence of required external compensation or bootstrap capacitors.
• On-board high-side driver capable of sourcing 0.35A.

Applications

• High-power car radio systems
• Automotive infotainment audio amplification
• Vehicle cabin sound reinforcement

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm package orientation and pinout compatibility. Ensure the selected variant matches the required thermal dissipation characteristics for the target application environment. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing automotive audio systems requiring high output power into low impedance loads such as 2Ω speakers. The integrated protections simplify design complexity by reducing the need for external circuitry. Consider the Flexiwatt 25 package constraints for thermal management and PCB layout requirements in confined vehicle spaces.

Part Context

The TDA7560H belongs to STMicroelectronics' family of automotive audio power amplifiers built on BCD technology. It serves as an upgrade or alternative to earlier models like the TDA7560, offering enhanced power delivery capabilities within the same functional framework. This series targets the demanding power and distortion requirements of modern vehicle entertainment systems.

Replacement Considerations

The E-TDA7560 is listed as a direct replacement option by distributors. Verify pinout and thermal performance equivalence before substitution. No other officially confirmed substitute part numbers are available in the provided documentation.
