TDA7569BLV

Overview

The TDA7569BLV is a quad bridge Class-AB audio power amplifier utilizing Multipower BCD technology. It delivers up to 4x50W output with high efficiency and low voltage operation capabilities, supporting start-stop profiles down to 6V. The device features full I2C diagnostics for speaker status monitoring, DC offset detection, and short circuit protection. Designed for automotive environments, it operates within a supply voltage range of 6V to 18V and withstands temperatures from -40°C to +105°C.

Feature Summary

• Integrated full I2C bus diagnostics for independent front/rear soft play/mute and load detection
• Patented Class SB high-efficiency solution significantly reduces dissipated output power compared to conventional Class AB designs
• Robust against misconnections and compliant with OEM specifications for low voltage start-stop battery profiles
• Advanced protection suite including linear thermal shutdown, clipping detector, and four independent short circuit protections

Applications

• Quad bridge car radio amplifiers
• Automotive infotainment systems requiring low voltage operation
• Start-stop compatible vehicle audio architectures

Procurement Notes

Verify the specific suffix (e.g., BLV vs. PDTR) to confirm package type and reel configuration. Ensure compatibility with AEC-Q100 qualification requirements for your target automotive application. Confirm that the selected variant matches the required mounting style, whether through-hole or surface mount, before finalizing procurement orders.

Selection Notes

Select this component when designing automotive audio systems requiring integrated digital diagnostics via I2C. It is suitable for applications needing high robustness against electrical transients and misconnections. Consider its low voltage capability if the design must support engine stop-start functionality without performance degradation.

Part Context

This part belongs to STMicroelectronics' family of advanced BCD technology quad bridge car radio amplifiers. It represents an evolution in automotive audio ICs by combining high power output with comprehensive digital control features. The series is designed to meet modern OEM demands for emission reduction through efficient power management.

Replacement Considerations

Check datasheets for TDA75610DLVPD or TDA7569BDLVPD as potential functional equivalents within the same diagnostic family. Verify pinout compatibility and thermal characteristics before substituting.
