TDA7569BLVH

Overview

The TDA7569BLVH is a four-channel Class SB audio power amplifier designed for automotive applications. It delivers 4 x 50 W output into 4 Ohm loads with a supply voltage range of 6 V to 18 V. The device features high efficiency, low voltage operation, and full I2C diagnostics. It operates within a temperature range of -40°C to +105°C and meets AEC-Q100 qualification standards.

Feature Summary

• Integrates MOSFET output power stage using Multipower BCD technology
• Provides comprehensive fault detection via full I2C diagnostic interface
• Optimized for high efficiency and low voltage automotive environments

Applications

• Automotive audio systems
• Car door speaker amplification
• Vehicle center channel amplification

Procurement Notes

Verify the specific suffix (e.g., BLVH) against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the component meets AEC-Q100 requirements for your target automotive environment. Cross-reference ordering codes with STMicroelectronics documentation to avoid substitution errors in production.

Selection Notes

Select this component for designs requiring integrated diagnostics and high efficiency in space-constrained automotive enclosures. The Class SB topology offers improved performance over traditional Class AB at lower voltages. Verify that the PowerSO-36 package fits the PCB thermal management strategy.

Part Context

This part belongs to STMicroelectronics' TDA7569 family of multi-channel audio amplifiers. These devices are engineered specifically for the automotive sector, combining power delivery with intelligent monitoring capabilities. The series supports various channel configurations to simplify vehicle audio architecture design.

Replacement Considerations

Check for TDA7569BLVPDTR or TDA7569BLVSMTR if surface-mount tape-and-reel packaging is required instead of tube packaging. Confirm functional equivalence through official cross-reference lists before implementation.
