Overview
The TDA7563BPD is a Class-AB automotive audio amplifier manufactured by STMicroelectronics. It features four channels delivering up to 75W output power into a 2-ohm load, with a total harmonic distortion plus noise of 0.03%. The device operates on a single supply voltage ranging from 8V to 18V and provides an output current of 8A. It utilizes a PowerSO-36 package for surface mount installation and supports a wide operating temperature range from -55°C to +150°C.
Feature Summary
- Integrated I2C bus interface enabling full digital diagnostics, including DC and AC load detection, clipping detection, and thermal warnings.
- High-efficiency DMOS output stage structure designed to simplify thermal management in high-power car radio applications.
- Comprehensive protection mechanisms including independent short circuit protection for each channel, linear thermal shutdown, and ESD protection.
Applications
- Automotive multi-channel speaker amplification systems
- Car radio power amplifier modules
- Vehicle infotainment audio processing units
Procurement Notes
Verify the specific suffix (PD) against the manufacturer's latest datasheet to confirm package orientation and pinout compatibility. Confirm AEC-Q100 qualification status for your specific automotive grade requirements. Check current production status as older variants may be obsolete or replaced by updated series versions.
Selection Notes
Select this component when designing automotive audio systems requiring high power density and integrated diagnostic feedback via I2C. Ensure the design accommodates the PowerSO-36 package thermal dissipation needs. Verify that the system voltage remains within the 8V to 18V operational window for stable Class-AB performance.
Part Context
This part belongs to the TDA7563B family of multifunction quad power amplifiers. It is specifically engineered for automotive environments using Multipower BCD technology. The series is characterized by its ability to drive multiple speakers with low distortion while providing extensive fault monitoring capabilities through a standard digital bus interface.
Replacement Considerations
TDA7563APD is listed as a direct substitute, although it is marked as obsolete. Verify electrical pin compatibility and thermal characteristics before swapping. No other active substitutes are confirmed in the provided documentation.
