The TPS3700 wide-supply window voltage detector operates over a 1.8-V to 18-V range. The device has two high-accuracy comparators with an internal 400-mV reference and two open-drain outputs rated to 18 V for over- and undervoltage detection. The TPS3700 can be used as a window voltage detector or as two independent voltage monitors; the monitored voltage can be set with the use of external resistors.

OUTA is driven low when the voltage at INA+ drops below (VITP – VHYS), and goes high when the voltage returns above the respective threshold (VITP). OUTB is driven low when the voltage at INB– rises above VITP, and goes high when the voltage drops below the respective threshold (VITP – VHYS). Both comparators in the TPS3700 include built-in hysteresis for filtering to reject brief glitches, thereby ensuring stable output operation without false triggering.

The TPS3700 is available in a SOT-6 and a 1.5-mm × 1.5-mm WSON-6 package and is specified over the junction temperature range of –40°C to 125°C.
