The 619 ms typical timeout holds the processor in reset long enough for the main supply to stabilize after power-up, which covers most crystal oscillators and PLL lock times in a 5V system. ## Temperature grade and package fit Surface-mount only, supplied in tape and reel or cut tape. The RoHS3 compliance covers the EU directive exemption list — no lead, cadmium, or phthalates above the threshold. ## Active lifecycle and how to source it For volume purchases or blanket-order coverage, the part is quoted to order. The open-drain output and 4.63V threshold are fixed — no adjustable variants in this order code. The SOT-23-5 package is a single-source footprint; no pin-compatible second source is listed on the TI cross-reference for this exact threshold and timeout combination.","metaTitle":"Texas Instruments LP3470A463DBVR Simple Reset IC","metaDescription":"Active Texas Instruments LP3470A463DBVR simple reset/power-on reset IC. 4.63V threshold, 619ms timeout, open-drain output, SOT-23-5.

It monitors a 1.0V supply (vs 4.63V), has a 270 ns propagation delay instead of a 619 ms timeout, and operates only to 85°C ambient (vs 125°C junction). The output is also open drain but the TL7702BID offers both active-high and active-low outputs. They are not drop-in replacements — the threshold, timeout, and temperature range are mismatched for a 5V rail supervisor application."},{"question":"How can I order LP3470A463DBVR or check availability?","answer":"The LP3470A463DBVR is sourced to order through independent and authorized distribution.
