3V threshold supervisor for a single supply rail
The TPS3851H30EDRBR is a Texas Instruments Simple Reset/Power-On Reset IC that monitors a single 3V supply rail. 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.
