Outputs float when heat sink temperature reaches >110°C. Output switching resumes about 1s after temperature drops below the threshold. Under voltage protection Power shut down by under voltage on VS+ (supply voltage). Typical threshold Shutdown Restart 8.6V 11.3V Over current protection The over current protection is DC input voltage and temperature dependent but will allow full power 4Ω in 50°C ambient without over current protection. The over current protection will protect the amp outputs from short between them and short to DC input. It will not protect against short to GND. nENABLE Shut down input: CON1:5 "nENABLE” Shut down by: Leave pin floating Normal operation : Pull down to GND VS+ 200k nENABLE 1n nDIAG Status output: CON1:3 "nDIAG” nDIAG goes low during under voltage and over temperature
