DD • Pin-For-PinCompatibleWithMAX809 Thereafter, the supervisory circuit monitors V and DD • TemperatureRange: –40°Cto+85°C keeps RESET active as long as V remains below DD the threshold voltage V . An internal timer delays the IT APPLICATIONS return of the output to the inactive state (high) to ensure proper system reset. The delay time, t = d(typ) • ApplicationsUsingDSPs,Microcontrollers,or 200 ms, starts after V has risen above the DD Microprocessors threshold voltage V . When the supply voltage drops IT • WirelessCommunicationSystems below the threshold voltage V , the output becomes IT active (low) again. No external components are • Portable/Battery-PoweredEquipment required. All the devices of this family have a fixed • ProgrammableControls sense-threshold voltage V set by an internal voltage IT • IntelligentInstruments divider. • IndustrialEquipment The product spectrum is designed for supply voltages • Notebook/DesktopComputers of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available in a 3-pin SOT-23. The TPS3809 devices • AutomotiveSystems are characterized for operation over a temperature rangeof–40°Cto85°C.

Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. Addendum-Page 1

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
