Product details

1.4V threshold — the supply rail it watches

When the monitored supply drops below that level, the active-low open-drain output asserts reset and holds it for an adjustable timeout period. It is designed for systems that need a clean, glitch-free power-on reset sequence on a 1.2V or 1.5V core rail — common in low-voltage DSPs, FPGAs, and MCUs.

Temperature range and package — where it goes

The SOT-23-6 package keeps the footprint small, but the 0.95 mm pitch demands a clean PCB layout to avoid noise coupling on the sense input.

Frequently asked questions

What package is TPS3808G15DBVRG4 in?

It comes in a SOT-23-6 surface-mount package.

What is the difference between TPS3808G15DBVRG4 and TPS3808G15DBVR?

The G4 suffix indicates a lead-free (RoHS) and green-compliant version of the base TPS3808G15DBVR. Functionally identical — same threshold, same package, same temperature range. The G4 variant is the current standard offering for new designs requiring RoHS compliance.
