Texas Instruments  TPS3701DDCR

The TPS3701 wide-supply voltage window supervisor 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-drainoutputs (OUTA and OUTB) rated to 25 V for over- and undervoltage detection. Use the TPS3701 as awindow supervisor or as two independent voltage monitors; set the monitored voltage with the use ofexternal 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 thevoltage at the INB pin rises above the positive threshold, and goes high when the voltage dropsbelow the negative threshold. Both comparators in the TPS3701 include built-in hysteresis for noiserejection, thereby ensuring stable output operation without false triggering.

The TPS3701 is available in a SOT-6 package and is specified over the junctiontemperature range of –40°C to 125°C.
