Product details

Single-rail watchdog for 1.8V logic

The TPS3836E18DBVT is a simple reset/power-on reset IC from Texas Instruments that monitors a single voltage rail and holds the reset output active-low until the supply stabilizes above the 1.71V threshold.

Threshold and timeout — what they mean on the board

The 1.71V threshold is set for a 1.8V nominal supply rail — if that rail dips below 1.71V, even briefly, the reset asserts and stays low for at least 10ms after the rail recovers. That 10ms window is the minimum guaranteed; actual timeout can be longer but never shorter, so the downstream device sees a clean, glitch-free reset pulse.

Active production — no EOL shadow

Frequently asked questions

Is TPS3836E18DBVT active low or active high?

The reset output is active low — when the monitored voltage drops below the 1.71V threshold, the output goes low and stays low for at least 10ms after the rail recovers.
