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.","metaTitle":"STM811SW16F Simple Reset/Power-On Reset, 2.93V Threshold","metaDescription":"STM811SW16F Simple Reset/Power-On Reset IC.
