(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions
      for extended periods may degrade device reliability. These are stress ratings only, and functional operation
     of the device at these or any other conditions beyond those specified is not implied.
(2) The input and output voltage ratings may be exceeded if the input and output clamp-current ratings
      are observed.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.



Description

The TXS03121 is a comparator designed for battery monitoring applications. TXS03121 can be operated with a voltage of 3 V to 5.5 V. The reference voltage of TXS03121 is applied to the IN terminal, whereas the voltage to be monitored is connected to +IN. When the voltage at +IN is greater than the voltage at IN, the output FET is turned On. When the voltage at +IN is less than the voltage at IN, the output FET is turned Off. The source (S) of the output FET can be connected to 1.1 V to 3.6 V, which allows the output signal to be level translated to another voltage value. The voltage at V₊ must be greater than or equal to the voltage at S. The voltage at S must be greater than or equal to the voltage at D (V₊ V_S V_D).
