FDA802B-VYY

Overview

The FDA802B-VYY is a dual-bridge Class-D digital input automotive power amplifier manufactured by STMicroelectronics. It delivers 150 W per channel into a 4 Ω load or 300 W in bridge-tied-load (BTL) mode. The device operates within a supply voltage range of 5.5 V to 50 V and supports a minimum operating temperature of -40°C. It features a 64-lead LQFP package with an exposed pad for thermal management. The component holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Digital input interface for direct connection to audio processors
• Integrated I2C diagnostics for system monitoring and fault detection
• Automotive-grade construction compliant with AEC-Q101 standards

Applications

• Automotive center console speaker systems
• Vehicle door panel audio amplification
• High-fidelity car infotainment sound reinforcement

Procurement Notes

Verify the specific suffix VYY against the official datasheet to confirm pinout and packaging details. Confirm AEC-Q101 compliance requirements for your target automotive application. Check current availability status as automotive components may experience supply fluctuations. Ensure proper thermal design for the LQFP-64 package during integration.

Selection Notes

Select this model when high output power is required for dual-channel or BTL configurations in automotive environments. The digital input capability simplifies system architecture by reducing analog signal paths. Consider the 50 V maximum supply rating for compatibility with standard vehicle electrical systems. Evaluate the diagnostic features if system health monitoring is critical for the design.

Part Context

This component belongs to the FDA802 family of automotive power amplifiers from STMicroelectronics. The family includes variants such as FDA802S-VYT and FDA802P-VYT, which share similar Class-D architectures but differ in output power ratings and specific feature sets. All members are designed for robust performance in demanding vehicular audio applications.

Replacement Considerations

The FDA802B-VYT is a documented substitute within the same product family. Verify that the alternative variant meets the required output power and diagnostic specifications for the intended application before substitution.
