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.
