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.
