Abstract: This paper presents a system suitable for DfTT (Design for Thermal Testability) purposes that allows temperature monitoring and programmable overtemperature detection implemented in CMOS technology. It has been developed for on-line monitoring in automotive applications. The system includes a temperature sensor, based on the Base-emitter Voltage of a CMOS Lateral Bipolar Transistor, that achieves a non-linearity lower than 0,4 ?C in the range comprised between [-40 ?C, 85 ?C]. The system is compatible with the Boundary Scan protocol. The chip functions are discussed in detail.
