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 (V_ITP – V_HYS), and goes high when the voltage returns above the respective threshold (V_ITP). OUTB is driven low when the voltage at INB– rises above V_ITP, and goes high when the voltage drops below the respective threshold (V_ITP – V_HYS). 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.
