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-drain
outputs rated to 18 V for overvoltage and undervoltage detection. The TPS3700-Q1 device can be used
as a window comparator or as two independent voltage monitors; the monitored voltage can be set
with 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 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
