When the monitored voltage drops below the 3V threshold, the open-drain output pulls low and holds the reset state for a minimum of 170ms after the rail recovers — long enough for the downstream processor or FPGA to complete its power-on sequence. ## Industrial temperature grade and 8-SON footprint Surface-mount assembly with an 8-SON (3x3) exposed-pad footprint. The base product number TPS3851 spans multiple threshold-voltage options; the H30 suffix selects the 3V version. ## Sourcing and BOM-fit note The active lifecycle means this part is not subject to last-time-buy constraints, so volume commitments carry no near-term supply risk.","metaTitle":"TPS3851H30EDRBR Simple Reset/Power-On Reset, 3V Threshold","metaDescription":"Texas Instruments TPS3851H30EDRBR Simple Reset/Power-On Reset IC.
