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.
