Product details

The TPS3808G09DBVT monitors a single supply rail and asserts a reset when the voltage drops below 0.84V. That threshold is set for low-voltage cores (e.g., 0.9V or 1.0V rails) where a few millivolts of droop can corrupt state. The open-drain output lets you wire-OR with other supervisors or pull to any logic voltage up to the absolute maximum.

125°C junction — fits under-hood and industrial bays

The SOT-23-6 package is small enough for cramped PCBs but still reworkable with a hot-air station — the exposed pad is absent, so you lift the part without pulling the pad.

The SOT-23-6 package is widely stocked across distribution channels; lead time is typically a few weeks for volume, but we confirm per RFQ.

Frequently asked questions

Is the TPS3808G09DBVT active-low reset?

Yes, the reset output is active low. The open-drain output goes low when the monitored voltage drops below the 0.84V threshold and remains low for the adjustable timeout period after recovery.
