Product details

The TPS3808G30DBVR is a single-channel voltage supervisor that asserts a reset signal when the monitored supply drops below 2.79V. The open-drain output stays low until the supply recovers and the adjustable/selectable reset timeout expires. For a nominal 3.3V rail, the 2.79V threshold provides a brown-out window of roughly 0.5V below regulation — enough to catch a sag before logic glitches, without nuisance trips on normal ripple.

Temperature range and package for harsh environments

The SOT-23-6 package keeps the footprint small — 0.95 mm pitch, suitable for 2-layer boards with standard reflow profiles.

Frequently asked questions

How do I set the reset timeout on TPS3808G30DBVR?

The reset timeout is adjustable/selectable. A capacitor connected to the CT pin sets the delay; the datasheet provides the formula. The part does not have a fixed internal timeout — you choose it per the application.

Is TPS3808G30DBVR compatible with 3.3V logic?

Yes. The 2.79V threshold is appropriate for monitoring a 3.3V supply, and the open-drain output pulls to whatever pull-up voltage is used — typically the monitored rail or a separate 3.3V or lower logic supply.

What is the closest functional second-source to TPS3808G30DBVR?

The TLV803EA29VDBZR from Texas Instruments is a similar single-channel supervisor with an active-low, open-drain output and a 130 ms minimum reset timeout. Its threshold is 2.93V, so it triggers slightly higher on a 3.3V rail. The TLV803ED29DBZR offers a 33 ms minimum timeout. Neither is a drop-in replacement — verify the threshold and timeout match your design.
