TDA7563APDTR

Overview

The TDA7563APDTR is a quad bridge power amplifier designed for automotive applications, manufactured by STMicroelectronics. It operates on a single supply voltage ranging from 8V to 18V and utilizes the PowerSO-36 package with a top exposed pad for thermal management. The device delivers up to 72W per channel into a 2-ohm load and 50W per channel into a 4-ohm load at 1kHz with 10% THD. It features Class AB operation with high efficiency characteristics, I2C bus control for diagnostics and standby functions, and comprehensive protection mechanisms including short circuit, thermal shutdown, and DC offset detection.
