TPS3711 Wide-Supply Voltage Detector

Texas Instruments TPS3711 Wide-Supply Voltage Detector operates over a voltage range of 1.8V to 36V. The device has a precision comparator with an internal 400mV reference and an open-drain output rated to 25V for under-voltage detection. The monitored voltage can be set with the use of external resistors. OUT is driven low when the voltage at the SENSE pin drops below the negative threshold. The OUT goes high when the voltage returns above the positive threshold. The comparator in the TPS3711 includes a built-in hysteresis for noise rejection, thereby ensuring stable output operation without false triggering.
