The TPS3703-Q1 combines two comparators with a precision reference voltage and a trimmed resistor divider. This configuration optimizes device accuracy because all resistor tolerances are accounted for in the accuracy and performance specifications. Both comparators also include built-in hysteresis that provides noise immunity and ensures stable operation.

Although not required in most cases, for noisy applications good analog design practice is to place a 1-nF to 10-nF bypass capacitor at the SENSE input in order to reduce sensitivity to transient voltages on the monitored signal.

When monitoring VDD supply voltage, the SENSE pin can be connected directly to VDD. The output ( RESET) is high impedance when voltage at the SENSE pin is between upper and lower boundary of threshold.
