Fault
The FAULT output will be set low (0V) under the following conditions:
•
The amplifier has gone into thermal shutdown due to a measured high temperature
•
The amplifier has detected an overload condition on the speaker terminals
The FAULT output is located on the rear of the HSP unit. Connect the FAULT and GND connection to any external control solution to read this signal.
The FAULT output is an open collector output with a 390R current limiting resistor in series.
