STMicroelectronics TDA7389 Quad Bridge Car Radio Amplifier Datasheet
The document describes the TDA7389, an AB class audio power amplifier packaged in Flexiwatt 25. It is specifically designed for high-end car radio applications and features a fully complementary PNP/NPN configuration that allows rail-to-rail output voltage swing without bootstrap limiter capacitors.
Key specifications include four channels of up to 45W maximum output power at 14.4V supply. The device incorporates extensive protection mechanisms such as thermal shutdown, short-circuit detection (to GND and Vcc), load dump voltage protection, and reversed battery protection. It also features a standby function with automute capabilities.
