Product details

What this supervisor does on your board

The open-drain output pulls low within 5µs typical propagation delay after a fault, making it suitable for fast fault response rather than the longer timeout typical of simple power-on reset ICs.

Why the 5µs propagation delay matters

The adjustable second channel lets you monitor a non-standard rail (e.g., 1.8V, 2.5V, or an auxiliary supply) alongside the fixed 3V threshold, reducing component count versus using two separate supervisors.

Temperature grade and board fit

Surface-mount SOT-23-6 with 0.95mm pitch is a two-layer-friendly package; no special fan-out needed for most layouts.

Frequently asked questions

What is the closest functional second-source for TPS3806I33DBVT?

The TLV803EA29VDBZR is a simple reset/power-on reset IC with an active-low open-drain output, but its reset timeout is 130ms minimum versus the 5µs propagation delay of the TPS3806I33DBVT. The TLV803 also monitors a single rail at 2.93V fixed, not two channels. For a dual-voltage supervisor with fast response, the TPS3806I33DBVT has no direct pin-compatible second-source in the TLV803 series.
