The SENSE1 and • Low Quiescent Current: 2 µA (typ) SENSE2 inputs include hysteresis to reject brief glitches, ensuring stable output operation without • Adjustable Detection Voltage Down to 1.2 V false triggering. This family offers different factory-set • Multiple Hysteresis Options: hysteresis options of 0.5%, 1%, 5%, or 10%. – 0.5%, 1%, 5%, and 10% The TPS3779 and TPS3780 have adjustable SENSE • Temperature Range: –40°C to 125°C inputs that can be configured by an external resistor • Push-Pull (TPS3779) and Open-Drain (TPS3780) divider. When the voltage at the SENSE1 or SENSE2 Output Options input goes below the falling threshold, OUT1 or OUT2 is driven low, respectively. When SENSE1 or • Available in µSON and SOT23 Packages SENSE2 rises above the rising threshold, OUT1 or OUT2 goes high, respectively. 2 Applications The devices have a very low quiescent current of • DSP, Microcontroller, and Microprocessor 2 µA (typical) and provide a precise, space-conscious Applications solution for voltage detection suitable for low-power • Portable Medical Devices system-monitoring and portable applications. The • Building Automation TPS3779 and TPS3780 operate from 1.5 V to 6.5 V, over the –40°C to 125°C temperature range. • Set-Top Boxes • Solid-State Drives Device Information(1) • Notebook and Desktop Computers PART NUMBER PACKAGE BODY SIZE (NOM) • Portable and Battery-Powered Products µSON (6) 1.45 mm × 1.00 mm TPS37xx • Power-Supply Sequencing Applications SOT23 (6) 2.92 mm × 1.30 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
