When the monitored supply drops below that threshold, the active-low open-drain output asserts reset and holds it for a minimum of 100ms after the rail recovers — long enough for the downstream MCU or DSP to complete its power-on reset sequence. ## Active lifecycle and sourcing posture The part is ROHS3 compliant. For current pricing and availability, submit an RFQ; we source through independent distribution and confirm lot traceability and manufacturer warranty at quote time. Housed in a SOT-23-6 (SOT-6 supplier package) surface-mount package. The 100ms minimum reset timeout is a fixed internal delay; no external capacitor is needed to set the timeout.","metaTitle":"MAX6343MUT+T Analog Devices Simple Reset/Power-On Reset","metaDescription":"MAX6343MUT+T simple reset/power-on reset supervisor, active-low open-drain output, 4.38V threshold, 100ms timeout, SOT-23-6, -40°C to 125°C.","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":"SOT-23-6","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.38V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.64","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.64000","currency":"USD"},{"qty":10,"price":"$3.26900","currency":"USD"},{"qty":25,"price":"$3.09040","currency":"USD"},{"qty":100,"price":"$2.67850","currency":"USD"},{"qty":250,"price":"$2.54116","currency":"USD"},{"qty":500,"price":"$2.28018","currency":"USD"},{"qty":1000,"price":"$1.92304","currency":"USD"},{"qty":2500,"price":"$1.82689","currency":"USD"},{"qty":5000,"price":"$1.75821","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What does the 4.38V threshold mean for my 5V rail?","answer":"The 4.38V threshold is the falling trip point — when the monitored 5V supply drops below 4.38V, the reset output asserts. This is typical for a 5V nominal rail with a ±10% tolerance window, catching brownouts before the logic supply drops out of the guaranteed operating range."},{"question":"What is the output type and how do I use it?","answer":"The reset output is open-drain, active low. Connect a pull-up resistor (typically 10 kΩ to 100 kΩ) to the logic supply voltage. The output holds low during the reset timeout and releases to high-impedance when the supply is above the threshold and the timeout expires."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6343MUTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6343MUTT when reusing this data.
