TDA7385
Features
■ High output power capability:
– 4 x 42 W / 4 Ω max.
– 4 x 23 W / 4 Ω @ 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
