Product details

2.25 V threshold supervisor in SOT-23-6

This threshold is tailored for 2.5 V logic rails — common in MCU, FPGA, and DSP core supplies — where a clean power-up sequence is critical.

20 ms minimum reset timeout — what it buys you

The reset output stays low for a minimum of 20 ms after the supply crosses the threshold. That window gives the power rail time to settle and the oscillator to stabilise before the processor fetches its first instruction. In a typical 2.5 V rail with a 10 µF bypass cap, the 20 ms timeout covers the ramp-up transient even with a slow-start regulator.

The SOT-23-6 package is a 6-lead surface-mount footprint with 0.95 mm pitch — easy to hand-solder or reflow, and the small body (3.0 mm × 3.0 mm) fits tight layouts.

Frequently asked questions

Is TPS3813J25DBVT pin-compatible with TPS3813J33DBVT?

Yes, the TPS3813J25DBVT and TPS3813J33DBVT share the same pinout and SOT-23-6 package. The only difference is the voltage threshold: 2.25 V for the J25 variant versus 3.3 V for the J33 variant. If your design uses a 2.5 V rail, the J25 is the correct threshold; for a 3.3 V rail, use the J33. Both are active and available.

What is the reset timeout of TPS3813J25DBVT?

The reset timeout is a minimum of 20 ms. This is the guaranteed low time of the reset output after the monitored voltage rises above the 2.25 V threshold.

Does TPS3813J25DBVT have an open drain output?

Yes, the output is open drain or open collector. This allows the reset signal to be pulled up to a voltage independent of the monitored rail, and it supports wired-OR connections with other open-drain reset sources.
