3 Description
The TPS3711 wide-supply voltage comparator
operates over a 1.8-V to 36-V range. The device has
a precision comparator with an internal 400-mV
reference and an open-drain output rated to 25 V for
undervoltage detection. Set the monitored voltage
with the use of external resistors.
OUT is driven low when the voltage at the SENSE
pin drops below the negative threshold, and goes
high when the voltage returns above the positive
threshold. The comparator in the TPS3711 includes
built-in hysteresis for noise rejection, thereby
ensuring stable output operation without false
triggering.
The TPS3711 is available in a SOT-6 package, and is
specified over the junction temperature range of
–40°C to +125°C.
