Product details

2.93 V threshold — the brown-out trip point that matters

The STM811SW16F is a single-channel voltage supervisor from STMicroelectronics, built for simple reset/power-on reset duty. The reset is active low, push-pull, so it drives directly into the reset pin of most MCUs without an external pull-up. The 140 ms minimum reset timeout holds the processor in reset long enough for the supply and oscillator to stabilise after power-up.

ROHS3 compliant.

Package and mounting — SOT-143-4, surface-mount only

Supplied in a SOT-143-4 surface-mount package. The TO-253-4 / TO-253AA case code is the same footprint. Standard reflow profile for a small-outline transistor package applies — no special handling beyond MSL precautions.

Frequently asked questions

What is the STM811SW16F reset timeout?

The reset timeout is 140 ms minimum. After the supply rises above the threshold, the reset output stays low for at least 140 ms before releasing.

What is the STM811SW16F equivalent or second source?

The STM706M6F also shares those parametrics. Both are drop-in candidates for dual-sourcing.
