3 Description
The TPS3701 wide-supply voltage window detector
operates over a 1.8-V to 36-V range. The device has
two precision comparators with an internal 400-mV
reference and two open-drain outputs (OUTA and
OUTB) rated to 25 V for over- and undervoltage
detection. Use the TPS3701 as a window voltage
detector or as two independent voltage monitors; set
the monitored voltage with the use of external
resistors.
OUTA is driven low when the voltage at the INA pin
drops below the negative threshold, and goes high
when the voltage returns above the positive
threshold. OUTB is driven low when the voltage at
the INB pin rises above the positive threshold, and
goes high when the voltage drops below the negative
threshold. Both comparators in the TPS3701 include
built-in hysteresis for noise rejection, thereby
ensuring stable output operation without false
triggering.
The TPS3701 is available in a SOT-6 package and is
specified over the junction temperature range of
–40°C to 125°C.
