Circuit is based on 103AT NTC thermistor connected to TS and VSS, and a 10k Ω resistor connected to VTB and TS. Actual thresholds must be determined in mV. Refers to the over- and under-temperature mV threshold in the Electrical Characteristics table. Unless specified, the devices in Table 1 and Table 2 are default with state comparator enabled with 2 mV threshold. Filtered fault detection is used by default.
