Texas Instruments TPS3701 36V Window Comparator
Texas Instruments TPS3701 36V Window Comparator is a wide-supply voltage window comparator that operates over a 1.8V to 36V range. The device has two precision comparators with an internal 400mV reference and two open-drain outputs (OUTA and OUTB) rated to 25V for over- and undervoltage detection. Use the TPS3701 as a window comparator or as two independent voltage monitors; set the monitored voltage with the use of external resistors.
OUTA is driven low when the voltage at the INA pin drops below the negative threshold, and goes high when the voltage returns above the positive threshold. OUTB is driven low when the voltage at the INB pin rises above the positive threshold, and goes high when the voltage drops below the negative threshold. Both comparators in the TPS3701 include built-in hysteresis for noise rejection, thereby ensuring stable output operation without false triggering.
