Product details

0.84V threshold supervisor in a SOT-23-6

It asserts a reset output when the supply drops below that threshold and holds it low for an adjustable timeout period after the rail recovers. The open-drain output lets you wire-OR it with other supervisors or pull it up to a different voltage domain. This part is built for low-voltage core rails — think 0.9V or 1.0V supplies powering an FPGA core, a DSP, or a modern MCU. The active-low reset signal is what most processors expect on their nRST pin. The adjustable timeout (set via an external capacitor) gives you flexibility to match the power-up settling time of the downstream device.

Temperature range and package — board-fit details

Surface-mount mounting, shipped in Tape & Reel (TR) — standard for automated pick-and-place. No exposed thermal pad to worry about; the junction-to-ambient thermal resistance is handled by the copper pad area on the PCB.

Frequently asked questions

What is the reset timeout of the TPS3808G09DBVTG4?

The reset timeout is adjustable or selectable via an external capacitor. The datasheet provides the capacitor-value-to-timeout relationship; the range covers milliseconds to several seconds depending on the capacitor chosen.

Can the TPS3808G09DBVTG4 replace the TPS3808G09DBVR?

The TPS3808G09DBVTG4 and TPS3808G09DBVR share the same base part number (TPS3808) and the same 0.84V threshold. The suffix difference is packaging — the DBVTG4 is Tape & Reel, while the DBVR is typically in a different reel or tube configuration. Electrically they are identical; check the reel quantity and tape width for your assembly line.

Is the TPS3808G09DBVTG4 RoHS compliant?

The part is listed with a standard TI part number suffix that typically indicates RoHS compliance and green (halogen-free) status. The datasheet or TI's material declaration should confirm — no contradictory evidence in the listing.
