Beschreibung
Zusammenfassung:	A respiratory apparatus comprising a blower driven by a motor 4144 to generate a flow of breathable gas, at least one sensor 4272, 4274, 4278 configured to provide at least one input signal indicative of at least one of a physical and system parameter, a microprocessor 4230 configured to provide executable instructions to control the motor 4144, and a fault mitigation integrated circuit 4500 in communication with the motor 4144 and the microprocessor 4230. The fault circuit 4500 is configured to receive the at least one input signal from the at least one sensor, detect a fault based on the received at least one input signal, and generate an output signal to stop the motor based on the detected fault. The fault circuit 4500 is further configured to monitor any one or more of an input motor current, an input motor bus voltage, and an input temperature.
