Overview
The TDA7569BDLVPD is a quad bridge car radio amplifier utilizing Multipower BCD technology. It delivers 4x28 W into 4 Ω and 4x50 W into 2 Ω at 14.4 V with 10% THD. The device operates on a supply voltage range of 6 V to 18 V, supporting low voltage 'start-stop' profiles. It features Class SB high efficiency, differential inputs for improved disturbance rejection, and full I2C bus diagnostics including DC/AC load detection and clipping monitoring.
Feature Summary
- Full I2C bus driving with comprehensive digital diagnostics for speaker status and fault detection
- High output power capability with Class SB efficiency and differential input stage
- Robust protection against misconnections, short circuits, and thermal overload
- Low voltage operation compliance for start-stop battery profiles
Applications
- Automotive audio systems requiring high efficiency and low voltage operation
- Car radio amplifiers with integrated digital diagnostics
- Applications needing robust protection against battery transients and misconnections
Procurement Notes
Verify the specific suffix 'BLVPD' against official STMicroelectronics documentation to confirm package type and tape/reel specifications. Ensure compatibility with automotive environmental standards and I2C interface requirements before integration. Cross-reference datasheet revisions for any updates to diagnostic features or electrical characteristics.
Selection Notes
Select this component for designs requiring a quad bridge amplifier with extensive I2C-based diagnostics. It is suitable for applications demanding high efficiency in low voltage environments, such as modern vehicles with start-stop functionality. Consider the PowerSO-36 package constraints and thermal management requirements for the specified power outputs.
Part Context
This part belongs to the TDA7569 family of advanced BCD technology quad bridge car radio amplifiers. It shares core functionalities with variants like TDA7569BLV but differs in packaging and delivery format. The family is designed to meet OEM specifications for low voltage operation and emissions reduction through high efficiency.
Replacement Considerations
TDA7569BLV is a related variant within the same family offering similar electrical performance but potentially different packaging or termination options. Verify pinout compatibility and thermal characteristics when substituting.
