The SENSE1 and SENSE2 1.0% inputs include a built-in hysteresis for filtering to reject brief glitches, thereby ensuring stable output • Adjustable Thresholds operation without false triggering. This family offers • Different Hysteresis Options: different factory-set hysteresis options of 0.5%, 1%, – 0.5%, 1%, 5%, and 10% 5%, or 10%. • Temperature Range: –40°C to +125°C The TPS3779 and TPS3780 have adjustable SENSE • Push-Pull (TPS3779) and Open-Drain inputs that can be configured by an external resistor divider. When the voltage at the SENSE1 or SENSE2 (TPS3780) Output Options input goes below the falling threshold, OUT1 or OUT2 is driven low, respectively. When SENSE1 or APPLICATIONS SENSE2 rises above the rising threshold, OUT1 or • DSPs, Microcontrollers, or Microprocessors OUT2 goes high, respectively. Applications The devices have a very low quiescent current of • Portable and Battery-Powered Products 1.8 µA (typical) and provide a precise, space- • Cell Phones and PDAs conscious solution for voltage detection suitable for low-power system-monitoring and portable • Notebook and Desktop Computers applications. The TPS3779 and TPS3780 operate • Set-Top Boxes from 1.5 V to 6.5 V, over the –40°C to +125°C temperature range. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
