Product details

The TPS3813K33DBVT is a simple reset IC from Texas Instruments that monitors a single supply rail and asserts an active-low, open-drain reset when the voltage drops below 2.93 V. That threshold is set for a nominal 3.3 V supply — it triggers at roughly 89% of nominal, so the reset fires before the downstream logic sees a brownout. The reset stays low for a minimum of 20 ms after the rail recovers, giving the supply time to stabilise before the processor starts.

The SOT-23-6 package is a 6-pin surface-mount footprint, 2.9 mm × 1.6 mm body, so it fits on tight mixed-signal boards without eating layout space.

Frequently asked questions

Is TPS3813K33DBVT compatible with 3.3 V systems?

Yes. The 2.93 V threshold is designed for a 3.3 V supply rail — it asserts reset at roughly 89% of nominal, which is a standard undervoltage detect point for 3.3 V logic.

What is the difference between TPS3813K33DBVT and TPS3813K33DBVR?

Both share the same die and electrical specs — the difference is the shipping medium. The DBVT suffix indicates Tape & Reel packaging; the DBVR suffix indicates a different reel quantity or cut-tape option. The device itself is identical.
