TDA7575B

Overview

The TDA7575B is a Class-AB dual-bridge audio power amplifier designed for automotive applications. It delivers up to 2x75W into 2 Ohms or 1x150W into 1 Ohm. The device features differential inputs, 26 dB gain, and operates on a single supply voltage between 8V and 18V. It includes integrated I2C diagnostics, short-circuit protection, and thermal shutdown. The component is housed in a PowerSSO-36 package and meets AEC-Q100 qualification standards.

Feature Summary

Dual-bridge architecture with MOSFET output stage for high efficiency and low distortion
Integrated digital diagnostics via I2C bus for speaker status monitoring
Supports single-channel 1 Ohm driving capability by paralleling outputs
Comprehensive fault protection including DC offset detection and clipping detection

Applications

Automotive car radio systems
In-vehicle infotainment audio amplification
High-power automotive sound sets requiring simplified thermal management

Procurement Notes

Verify the specific suffix (e.g., BPD, PDTR) against the required packaging format such as tube or reel. Confirm AEC-Q100 automotive qualification requirements are met for the target application environment. Ensure compatibility with the host controller's I2C interface for diagnostic functionality.

Selection Notes

Select this component for designs requiring high output power in a compact form factor. Consider the PowerSSO-36 package for surface-mount assembly. Evaluate thermal dissipation needs given the Class-AB operation at high power levels. Verify that the load impedance matches the amplifier's specified capabilities for optimal performance.

Part Context

Part of the TDA7575B series of automotive audio amplifiers. Designed to replace conventional Class-AB solutions with improved efficiency. Part of STMicroelectronics' portfolio for smart driving and infotainment systems.
