Fan cooling may be required continuously, or during peak power demands, e.g. for a power supply, and if the cooling systems fails, system reliability and/or safety may be impaired. By monitoring temperature while emulating a power IC, the TMP12 can provide a warning of cooling system failure. The TMP12 generates an internal voltage that is linearly proportional to Celsius (Centigrade) temperature, nominally 5 mV/°C. The linearized output is compared with vol……
