TDA7563ASMTR

Overview

The TDA7563ASMTR is a four-channel Class SB automotive power amplifier manufactured by STMicroelectronics. It delivers up to 4 x 50 W maximum output power and 4 x 28 W into 4 Ω loads at 14.4 V with 10% THD. The device utilizes Multipower BCD technology and DMOS output stages for high efficiency and low distortion. It features built-in I2C diagnostics, including DC/AC load detection, short circuit protection, and thermal warnings.

Feature Summary

• High-efficiency Class SB architecture utilizing DMOS output stages for superior thermal management compared to conventional Class AB solutions.
• Integrated I2C bus interface enabling full digital diagnostics, independent channel monitoring, and selectable gain configurations.
• Comprehensive fault protection suite including four independent short-circuit protections, DC offset detection, and linear thermal shutdown with multiple warning levels.

Applications

• Automotive radio systems requiring high-power audio amplification
• Modern vehicle infotainment and cabin sound systems
• Car audio setups demanding simplified thermal management

Procurement Notes

Verify the specific suffix 'MTR' against official STMicroelectronics documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with Flexiwatt27 or PowerSO36 mounting requirements as indicated in related datasheets. Confirm that the I2C diagnostic functionality aligns with the target system's communication protocol before integration.

Selection Notes

Select this component for applications prioritizing high output power efficiency and integrated digital diagnostics. The Class SB topology reduces dissipated power significantly under average listening conditions. Verify that the design supports the required I2C bus driving capabilities for standby and mute functions.

Part Context

This part belongs to the TDA7563 family of multifunction quad power amplifiers designed specifically for car radio applications. The series leverages Multipower BCD technology to provide clear, powerful sound with minimal distortion. Related variants include the TDA7563A and TDA7563B, which share similar architectural features but may differ in specific package options or diagnostic implementations.

Replacement Considerations

The TDA7563A and TDA7563B are confirmed substitutes within the same product family. Both variants offer identical core functionalities, including Class SB efficiency and I2C diagnostics. Verify package compatibility (Flexiwatt27 or PowerSO36) when substituting.
