TDF8541

I2C-bus controlled 4

 45 W power amplifier

 Temperature controlled gain reduction to prevent audio holes at high junction

temperatures

 Programmable low battery voltage detection to enable 7.5 V or 6 V minimum battery

voltage operation

 Overvoltage protection (load-dump safe up to VP = 50 V) with overvoltage pre-warning

at 16 V

 Offset detection
