8.5.6 Undervoltage Lockout

The TMP43x sense when the power-supply voltage has reached a minimum voltage level for the ADC to function. The detection circuitry consists of a voltage comparator that enables the ADC after the power supply (V+) exceeds 2.45 V (typical). The comparator output is continuously checked during a conversion. The TMP43x do not perform a temperature conversion if the power supply is not valid. The last valid measured temperature is used for the temperature measurement result.
