TDA7563BPDTR

Overview

The TDA7563BPDTR is a quad bridge-type Class AB audio power amplifier manufactured by STMicroelectronics, designed for automotive applications. It operates on a single supply voltage ranging from 8V to 18V and utilizes a PowerSO-36 package with an exposed top pad for thermal management. The device delivers up to 72W per channel into a 2-ohm load. Key electrical parameters include a maximum quiescent current of 300mA at 14.4V and a typical operating temperature range of -55°C to 150°C junction temperature.

Feature Summary

• Integrates full I2C bus control for standby, mute, gain selection, and digital diagnostics including DC/AC load detection.
• Features comprehensive protection mechanisms such as independent short circuit protection, linear thermal shutdown, and clipping detection.
• Employs Multipower BCD technology with DMOS output stages to achieve high efficiency and low distortion in automotive environments.

Applications

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

Procurement Notes

Verify the specific suffix PDTR indicates tape and reel packaging when sourcing. Confirm RoHS3 compliance status for environmental regulations. Check component availability as product status may vary. Ensure the PowerSO-36 package footprint matches the design layout. Validate that the I2C interface requirements align with the system controller.

Selection Notes

Select this component for designs requiring high output power with integrated thermal management via the exposed pad. Consider the I2C diagnostic capabilities for advanced system monitoring needs. Evaluate the 2-ohm driving capability against speaker impedance specifications. Assess the need for Class AB linearity versus other amplifier classes based on audio quality requirements.

Part Context

This part belongs to the TDA7563 family of multifunction quad power amplifiers. It shares core architecture with variants like TDA7563BPD but differs in packaging format. The series is characterized by its use of BCD technology for robust automotive performance. It serves as a specialized solution for complex audio distribution in modern vehicles.

Replacement Considerations

TDA7563BPD is a pin-compatible alternative in tube packaging. Verify if the change in packaging affects assembly processes or thermal dissipation characteristics. Ensure functional equivalence regarding I2C commands and protection thresholds before substitution.
