DESCRIPTION/ORDERING INFORMATION
The TXS03121 is a comparator designed for battery monitoring applications. It can be operated with a voltage of
3 V to 5.5 V. The reference voltage 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).
