Overview
The TDA7569BDLVPDTR is a quad bridge car radio amplifier utilizing Multipower BCD technology and DMOS output stages. It operates within a supply voltage range of 6.0 V to 18 V and supports an operating temperature range from -40°C to +105°C. The device delivers high output power, rated at 4x28 W into 4 Ω loads and 4x50 W into 2 Ω loads at 14.4 V with 10% THD. It features differential inputs, selectable gain of 16 dB or 26 dB, and full I2C bus diagnostics for comprehensive system monitoring.
Feature Summary
- Integrates complete I2C bus digital diagnostics including DC bias, AC load detection, and clipping detector pin with selectable thresholds.
- Features independent front/rear soft play/mute capabilities and standby mode control via the I2C interface.
- Includes robust protection mechanisms such as four independent short circuit protections, linear thermal shutdown, and ESD protection.
- Supports low voltage operation down to 6 V, enabling functionality during start-stop vehicle profiles.
Applications
- Automotive audio systems requiring high efficiency Class SB amplification
- Car radio designs with integrated digital diagnostic requirements
- Vehicle infotainment systems supporting start-stop technology
Procurement Notes
Verify the specific suffix DTR indicates tape and reel packaging configuration. Confirm AEC-Q100 automotive qualification status through official STMicroelectronics documentation. Ensure compatibility with existing I2C bus architectures in target vehicle platforms before integration.
Selection Notes
Select this component for applications requiring differential input stages and comprehensive fault detection via I2C. Consider the PowerSO-36 package for thermal management needs. Evaluate the 6 V minimum operating voltage requirement against vehicle electrical specifications to ensure reliable performance during cranking or low-battery conditions.
Part Context
This part belongs to the TDA7569 family of advanced BCD technology quad bridge car radio amplifiers. It shares functional similarities with the TDA7569BLV but differs in packaging and delivery format. The series is designed for high-efficiency audio applications in modern automotive environments.
Replacement Considerations
The TDA7569BLV is a related variant within the same product family. Verify if the specific packaging differences between the tube and tape-and-reel options meet assembly line requirements without altering electrical performance.
