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.
