These thresholds are target based on temperature, but they are dependent on external components that could vary based on customer

selection. 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. Contact Texas Instruments for new configuration option or

device in preview.
