1 / 14 page  November 2007 Rev 1 1/14 1 TDA7389A 4 x 45W quad bridge car radio amplifier Features ■ High output power: –4 x 45W/4 Ω max. –4 x 28W/4 Ω @ 14.4V, 1KHz, 10% ■ Low distortion ■ Low output noise ■ Stand-by function ■ Mute function ■ Automute at min. supply voltage detection ■ Low external component count: – Internally fixed gain (26dB) – No external compensation – No bootstrap capacitors ■ Clipping detector ■ Offset detector ■ Diagnostic facility for: – Out to GND short – Out to VS short – Thermal shutdown Protections: ■ Output short circuit to GND, to VS, across the load ■ Very inductive loads ■ Overrating chip temperature with soft thermal limiter ■ Load dump voltage ■ Fortuitous open GND ■ Output DC offset detector ■ Reversed battery ■ ESD Description The TDA7389A is a new technology class AB Audio Power Amplifier in Flexiwatt 27 package designed for high end car radio applications. Thanks to the fully complementary PNP/NPN output configuration the TDA7389A allows a rail to rail output voltage swing with no need of bootstrap capacitors. Flexiwatt27 Table 1.
