TDA7389 Quad BTL output power amplifier with stand-by and mute inputs, clip detection

The TDA7389 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed for high end car radio applications.

Based on a fully complementary PNP/NPN configuration the TDA7389 allows a rail to rail output voltage swing with no need of bootstrap capacitors.

High output power:
- 4 x 45 W / 4 Ω max.
- 4 x 28 W /4 Ω @ 14.4 V, 1 kHz, 10 %
Low distortion
Low output noise
Standby function
Mute function
Automute at min. supply voltage detection
Low external component count:
- Internally fixed gain (26 dB)
- No external compensation
- No bootstrap capacitors
Clipping 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
- Reversed battery
- ESD
