FEATURES
● High output power capability: – 4 x 42 W / 4 max. – 4 x 23 W / 4 @ 14.4 V, 1 kHz, 10 %● Clipping detector
● Low distortion
● Low output noise
● Standby function
● Mute function
● Automute at min. supply voltage detection
● Diagnostics facility for: – Clipping – Out to GND short – Out to VS short – Thermal shutdown
● Low external component count: – Internally fixed gain (26 dB) – No external compensation – No bootstrap capacitors
● 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 '!0'03 Flexiwatt25 – Reversed battery – ESD
DESCRIPTION
Based on a fully complementary PNP/NPN configuration, the TDA7385 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The fault diagnostics makes it possible to detect mistakes during carradio assembly and wiring in the car. Table 1. Device summary Order code Package TDA7385 E-TDA7385(1) Flexiwatt25 Flexiwatt25 1.
