Texas Instruments  TPS3700QDDCRQ1

The TPS3700-Q1 wide-supply voltage window comparator 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-drainoutputs rated to 18 V for overvoltage and undervoltage detection. The TPS3700-Q1 device can be usedas a window comparator or as two independent voltage monitors; the monitored voltage can be setwith the use of external resistors.

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

The TPS3700-Q1 device is available in a
ThinSOT23-6 package and is specified over the junction temperature range of –40°C to125°C.
