It is designed for power-on reset generation in systems where the supply rail must be held in reset until it stabilises above the threshold for at least 100ms. ## What the threshold and timeout mean for your design The 4.63V threshold is a precision trip point for 5V nominal rails — it asserts reset when VCC drops below this level, protecting downstream logic from brownout or power-up glitches. The open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button — the pull-up resistor goes to the monitored rail or any logic supply up to the absolute maximum rating. Active-low polarity matches the reset input of most MCUs and DSPs without an inverter. ## SOT-23-3 footprint and board integration Housed in a 3-pin SOT-23-3 (TO-236-3, SC-59), the MAX6348UR46+T occupies minimal board area — the footprint is 2.9mm × 1.3mm with 0.95mm pin pitch. Surface-mount assembly is straightforward with standard reflow profiles; no exposed pad or thermal management is needed at the ~10µA quiescent current. Available in Tape & Reel (TR) or Cut Tape (CT) packaging — the reel format suits automated pick-and-place for volume production, while cut tape works for prototyping and low-volume builds.","metaTitle":"MAX6348UR46+T Analog Devices Supervisor IC, 4.63V Threshold","metaDescription":"MAX6348UR46+T Analog Devices Simple Reset/Power-On Reset IC, 4.63V threshold, active-low open-drain output, 100ms min timeout, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.63V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.63","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.63000","currency":"USD"},{"qty":10,"price":"$4.15900","currency":"USD"},{"qty":25,"price":"$3.93160","currency":"USD"},{"qty":100,"price":"$3.40720","currency":"USD"},{"qty":250,"price":"$3.23252","currency":"USD"},{"qty":500,"price":"$2.90052","currency":"USD"},{"qty":1000,"price":"$2.44622","currency":"USD"},{"qty":2500,"price":"$2.32391","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the reset threshold and timeout of MAX6348UR46+T?","answer":"The threshold voltage is 4.63V for monitoring a 5V rail.
