Overview
The TDA7569BLVPDTR is a quad bridge car radio amplifier utilizing Multipower BCD technology. It operates within a supply voltage range of 6V to 18V and supports load impedances of 2 Ohms and 4 Ohms. The device delivers up to 50W per channel at 4 Ohms with Class-AB operation, or higher power in Class-SB mode. It features a PowerSO-36 surface-mount package with an exposed top pad for thermal management. The component functions across a temperature range of -40°C to 105°C and includes full I2C diagnostics.
Feature Summary
- Integrates full I2C bus diagnostics for independent front/rear soft play/mute control and DC/AC load detection.
- Designed for robust low-voltage operation compatible with start-stop battery profiles down to 6V.
- Includes comprehensive protection mechanisms such as linear thermal shutdown, four independent short circuit protections, and ESD protection.
Applications
- Quad bridge power amplification for automotive audio systems
- Car radio amplifier circuits requiring I2C diagnostic integration
- Low voltage vehicle electrical architectures
Procurement Notes
Verify the specific suffix PDTR indicates tape and reel packaging versus tube variants like BLV. Confirm AEC-Q100 qualification status for automotive reliability requirements. Ensure compatibility with the PowerSO-36 footprint and thermal pad soldering specifications during assembly.
Selection Notes
Select this component when high efficiency and low voltage operation are required for modern vehicle architectures. Consider the integrated I2C diagnostics for system monitoring needs. Evaluate the PowerSO-36 package constraints against available PCB real estate and thermal dissipation capabilities compared to through-hole alternatives.
Part Context
This part belongs to the TDA7569 family of advanced BCD technology quad bridge amplifiers. It represents an evolution over standard Class-AB solutions by offering significantly reduced dissipated output power under average listening conditions. The series is designed to meet recent OEM specifications for environmental protection and emission reduction.
