Overview
The TDA7569BLVPD is a quad bridge car radio amplifier utilizing Multipower BCD technology and Class-SB architecture. It delivers high output power, rated at 4x28 W into 4 Ohms at 14.4 V with 10% THD, and up to 4x45 W maximum power. The device supports operation down to 6 V for start-stop compatibility and features full I2C bus diagnostics. It includes selectable gain (16 dB or 26 dB), independent front/rear soft play/mute, and comprehensive protection against short circuits, thermal overload, and DC offset.
Feature Summary
- Class-SB high efficiency design reduces dissipated output power compared to conventional Class-AB solutions.
- Full I2C bus driving capability enabling remote control of standby, mute, and gain settings.
- Integrated digital diagnostics array communicates speaker status and detects faults such as DC load or AC open circuit.
- Robust protection mechanisms including four independent short circuit protections, linear thermal shutdown, and ESD protection.
Applications
- Automotive audio systems requiring low voltage operation during engine stop-start cycles
- Car radio amplifiers needing integrated digital diagnostics via I2C interface
- Vehicle infotainment setups utilizing differential power amplifier configurations
Procurement Notes
Verify the specific suffix 'LVPD' against official STMicroelectronics documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for PowerSO-36 packages. Confirm that the selected variant meets the required automotive qualification standards, such as AEC-Q100, for your specific application environment.
Selection Notes
Select this component when designing automotive audio systems that require high efficiency and advanced diagnostic capabilities. It is suitable for applications demanding operation under varying battery voltages, including low-voltage start-stop profiles. Consider the available gain options and I2C integration needs when evaluating this amplifier against other Class-AB or Class-D alternatives in the ST portfolio.
