Product details

1.71 V threshold — the reset trip point for a 1.8 V rail

That threshold is set for a nominal 1.8 V supply — the part holds the reset output active until the rail recovers above the threshold plus the built-in hysteresis, then releases after a 10 ms minimum timeout. The reset output is active high with a push-pull / totem-pole stage, so it drives an enable pin or a processor reset input directly without an external pull-up. If your design expects an active-low reset, this part won't work without an inverter.

SOT-23-5 — field-swappable footprint

Housed in a SOT-23-5 (SC-74A) package, this is a five-pin part with a 0.95 mm pitch — easy to hand-solder or swap on site with a standard iron. No hot-air station needed. The pinout is common across the TPS3837 family, so if you have the footprint on the board, the 1.8 V variant drops in.

Frequently asked questions

Is TPS3837E18DBVTG4 active high or active low reset?

It is active high reset. The output is push-pull, so it sources current when the reset is asserted — no external pull-up resistor needed. If your processor expects an active-low reset signal, you will need an inverter or a different part.
