TDA75610DLVPDTR

Overview

The TDA75610DLVPDTR is a quad bridge car radio amplifier utilizing Multipower BCD technology with DMOS power output. It delivers 4x25 W into 4 Ω at 14.4 V (1 kHz, 10% THD) and up to 4x45 W maximum power. The device operates on a supply voltage of 6V to 18V and features differential inputs for improved disturbance rejection. It includes full I2C bus diagnostics, selectable gain (26 dB/16 dB), and independent front/rear soft play/mute controls.

Feature Summary

• Full I2C bus digital diagnostics including DC/AC load detection, DC offset detection, and clipping detector pin with selectable thresholds.
• Class SB high efficiency design significantly reduces dissipated output power under average listening conditions compared to conventional Class AB solutions.
• Robust protection mechanisms include four independent short circuit protections, linear thermal shutdown with multiple warnings, and ESD protection.
• Compliant with low voltage operation specifications, capable of playing down to 6 V to support start-stop battery profiles.

Applications

• Automotive audio systems requiring high efficiency and low voltage operation
• Digital instrument clusters with integrated audio amplification
• Car radio amplifiers needing comprehensive speaker status diagnostics

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the component meets AEC-Q100 qualification requirements if automotive reliability standards are mandatory for the application. Ensure the design supports the required I2C interface for accessing the full diagnostic array.

Selection Notes

Select this component for applications demanding high output power with reduced heat dissipation. The differential input stage is suitable for environments with high electromagnetic interference. Verify compatibility with the system's I2C bus for accessing advanced features like independent mute control and fault detection.

Part Context

This part belongs to the TDA75610DLVPD series, which represents advanced BCD technology quad bridge amplifiers. It is designed to replace older Class AB solutions by offering higher efficiency and lower power consumption while maintaining robust performance in automotive electrical environments.

Replacement Considerations

Direct substitutes within the same family include TDA75610SLV and TDA75610LVPD. Verify package compatibility and pinout alignment before substitution. Ensure the replacement variant supports the required low voltage operation and diagnostic features.
