It is designed for microprocessor, microcontroller, and DSP systems that need a clean, glitch-free reset during power-up, brownout, or momentary supply dips. The reset output is active low and open-drain, so it can be pulled up to any voltage compatible with the downstream logic. The open-drain stage also lets multiple reset sources share a common pull-up resistor in a wired-OR configuration. With a 2.925 V threshold, this part monitors rails with margin to catch a brownout before the core logic drops out. The 140 ms minimum reset timeout holds the processor in reset long enough for the oscillator and PLL to stabilise after power returns. The SOT-23-5 package fits tight PCB layouts — typical for portable instruments, industrial sensors, and telecom line cards where board space is at a premium. The -40°C to 85°C operating range covers most factory-floor and outdoor cabinet environments. ## Sourcing and lifecycle The MAX6446UK29L+T is listed as Active in production — no end-of-life notice, no last-time-buy window. It is a current-generation part that can be specified into new designs without obsolescence risk. ROHS3 compliant, so it meets the latest EU restriction directives. No special handling or exemption paperwork needed for shipping into Europe or other ROHS-regulated regions.","metaTitle":"MAX6446UK29L+T Simple Reset/Power-On Reset, 2.925V Threshold","metaDescription":"MAX6446UK29L+T from Analog Devices is a simple reset/power-on reset IC with 2.925V threshold, active-low open-drain output, 140ms timeout, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"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":"140ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.925V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.92000","currency":"USD"},{"qty":10,"price":"$2.62200","currency":"USD"},{"qty":25,"price":"$2.53080","currency":"USD"},{"qty":100,"price":"$2.45730","currency":"USD"},{"qty":250,"price":"$2.40228","currency":"USD"},{"qty":500,"price":"$2.38394","currency":"USD"},{"qty":1000,"price":"$2.34726","currency":"USD"},{"qty":2500,"price":"$2.20056","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/max6443-max6452.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX6446UK29L+T have an open drain output?","answer":"Yes, the reset output is open drain (open collector).
