Product details

2.941V threshold — sizing the supervisor for a 3.3V rail

Its 2.941V threshold is set to assert a reset when a nominal 3.3V supply drops below that level, providing a clean power-fail or brown-out indication for the downstream processor or logic. The active-low, open-drain output stays low for a minimum of 65ms after the supply rises above the threshold, giving the system time to stabilise before the reset is released. This timeout is a fixed minimum — no external capacitor needed.

Temperature grade and package — board-fit for industrial environments

The SOT-23-6 package (supplier device package same as case) is a compact footprint for space-constrained designs, with surface-mount assembly standard.

Frequently asked questions

Is TPS3103K33DBVT compatible with 3.3V logic?

Yes. The 2.941V threshold is designed for a nominal 3.3V rail. The open-drain output can be pulled up to any voltage up to the absolute maximum of the output transistor, making it compatible with 3.3V logic inputs.

What is the difference between TPS3103K33DBVT and TPS3103K33DBVR?

The TPS3103K33DBVT and TPS3103K33DBVR are electrically identical. The suffix difference indicates the packaging and reel quantity: DBVT is typically Tape & Reel with a different reel size or quantity than DBVR. Confirm the exact reel quantity with your distributor for your assembly line's feeder setup.
