3 Description
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 (V_IT+ – V_hys), and goes
high when the voltage returns above the respective
threshold (V_IT+). The OUTB terminal is driven low
when the voltage at the INB– terminal rises above
V_IT+, and goes high when the voltage drops below the
respective threshold (V_IT+ – V_hys). 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
ThinSOT23-6 package and is specified over the
junction temperature range of –40°C to 125°C.
