TDA7567PDTR

Overview

The TDA7567PDTR is a quad bridge power amplifier utilizing Multipower BCD technology and DMOS output stages, designed for automotive applications. It delivers up to 4x50 W maximum power or 4x28 W at 4 Ω with 10% THD at 14.4 V. The device operates within an 8V to 18V supply range and features high efficiency class SB architecture. It includes full I2C bus diagnostics, independent front/rear soft play/mute, selectable gain (26 dB/16 dB), and comprehensive fault protection including short circuit, thermal shutdown, and DC offset detection.

Feature Summary

• High-efficiency class SB operation reduces thermal dissipation by up to 50% compared to conventional class AB solutions.
• Integrated full I2C digital diagnostics array monitors speaker status, detecting DC/AC load faults and clipping.
• Dual control modes allow operation via I2C bus or direct standby/mute pins with selectable addresses.

Applications

• Automotive infotainment systems
• Vehicle cabin audio amplification
• High-power car sound setups requiring simplified thermal management

Procurement Notes

Verify the specific suffix against official STMicroelectronics documentation to confirm package type and reel specifications. Ensure compatibility with automotive voltage ranges and I2C bus configurations before integration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component for designs requiring high output power with reduced heat generation in enclosed automotive environments. The differential input structure supports low-noise line outputs when configured with appropriate gain settings. Verify that the PowerSO-36 package fits the PCB layout constraints and thermal requirements of the target application.

Part Context

This part belongs to the TDA7567 family of multi-quad power amplifiers from STMicroelectronics. It shares core architectural features with variants like the TDA7567PD but differs in packaging and tape-and-reel configuration. The series is engineered specifically for demanding automotive audio applications requiring robust diagnostic capabilities and high reliability.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the TDA7563 series if different power classes are required. Verify pinout compatibility and thermal performance characteristics before replacing existing designs with similar STMicroelectronics amplifier models.
