Wide Supply Voltage Range: 1.8 V to 18 V
Adjustable Threshold: Down to 400 mV
High Threshold Accuracy:
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 over- and undervoltage
detection. The TPS3700 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.

Open-Drain Outputs for Overvoltage and
Undervoltage Detection
OUTA is driven low when the voltage at INA+ drops
below (VITP – VHYS), and goes high when the voltage
returns above the respective threshold (VITP). OUTB
is driven low when the voltage at INB– rises above
VITP, and goes high when the voltage drops below the
respective threshold (VITP – VHYS). Both comparators
in the TPS3700 include built-in hysteresis for filtering
to reject brief glitches, thereby ensuring stable output
operation without false triggering.
