The wide range means you don't need a separate industrial-grade variant for a motor drive or a base-station power supply. ## Package and mounting SC-70-3 is a tiny three-lead package. It's surface-mount and reworkable with hot air if the pad layout has decent thermal relief. ## Lifecycle and sourcing ROHS3 compliant.","metaTitle":"TLV803EB46DCKR Simple Reset/Power-On Reset, 4.63V Threshold","metaDescription":"TI TLV803EB46DCKR supervisor IC: active-low open-drain reset, 4.63V threshold, 40µs timeout, SC-70-3, -40°C to 125°C.

The output goes low when the supply drops below the threshold and stays low for the reset timeout period after recovery. Because it is open-drain, you need an external pull-up resistor to the logic supply."},{"question":"What is the reset timeout of TLV803EB46DCKR?","answer":"The reset timeout is 40µs typical. That is the duration the reset output stays low after the supply rises above the threshold — short enough to avoid holding the system in reset through a normal power-up sequence, but fast enough to catch brief brown-outs."},{"question":"Is TLV803EB46DCKR RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV803EB46DCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV803EB46DCKR when reusing this data.
