Overview
The TDA7563AEP-HLX is a quad bridge car radio amplifier utilizing Multipower BCD technology and DMOS output stages. It delivers 4 x 28 W at 4 Ω with 10% THD at 14.4 V, reaching 4 x 50 W maximum power. The device operates in Class SB for high efficiency, reducing thermal dissipation by up to 50% compared to Class AB. It features full I2C bus diagnostics, selectable gain of 26 dB or 12 dB, and comprehensive protection including short circuit, DC offset, and linear thermal shutdown.
Feature Summary
- High-efficiency Class SB operation reduces thermal management complexity
- Full I2C digital diagnostics for speaker status and fault detection
- DMOS output stage ensures low distortion and powerful sound
- Integrated protection against short circuits, DC offset, and overheating
Applications
- Car radio applications
- Automotive audio systems requiring high efficiency
- Digital cluster audio integration
Procurement Notes
Verify AEC-Q100 qualification status directly with STMicroelectronics before procurement. Confirm the specific HLX suffix functionality against official datasheets, as ordering suffixes may indicate package or temperature variations rather than functional changes. Ensure supply chain compatibility with Flexiwatt-27 or PowerSO-36 packaging requirements.
Selection Notes
Select this component for automotive designs prioritizing thermal efficiency over raw peak power. The Class SB architecture offers significant heat reduction compared to traditional Class AB amplifiers. Verify that the system supports I2C communication for accessing diagnostic features. Ensure the load impedance matches the specified 4 Ω or 2 Ω configurations for optimal performance.
Part Context
This part belongs to the TDA7563AEP series of quad bridge power amplifiers. It is designed specifically for automotive environments using BCD technology. The series includes variants like TDA7563A, tailored for car radio applications with integrated diagnostics and high output power capabilities.
Replacement Considerations
TDA7563A is the base model variant. Verify if the HLX suffix denotes a specific tape-and-reel or tube packaging option, as this affects handling but not electrical function.
