The TPS3700-Q1 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 overvoltage and undervoltage detection. The TPS3700-Q1 device 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. For even wider input voltage capability up to 65 V, see the TPS37A-Q1 or the TPS38A-Q1 devices.

The OUTA terminal is driven low when the voltage at the INA+ terminal drops below (VIT+ – Vhys), and goes high when the voltage returns above the respective threshold (VIT+). The OUTB terminal is driven low when the voltage at the INB– terminal rises above VIT+, and goes high when the voltage drops below the respective threshold (VIT+ – Vhys). Both comparators in the TPS3700-Q1 device include built-in hysteresis for filtering to reject brief glitches, thereby ensuring stable output operation without false triggering.

The TPS3700-Q1 device is available in a Thin SOT-6 and a 1.5-mm x 1.5-mm WSON-6 package and is specified over the junction temperature range of –40°C to 125°C.
