It asserts a reset signal when the monitored voltage drops below a user-set threshold, and holds reset for a typical 50µs after the supply recovers. ## 50µs reset timeout — fast enough for most MCUs The typical 50µs reset timeout is short enough that a microcontroller will have completed its internal reset sequence and be ready to execute code before the supervisor releases the reset line. That avoids spurious early-start issues. If your design needs a longer delay to let a power supply or oscillator stabilise, you would look at parts with programmable or fixed longer timeout windows — but for a straightforward power-on reset, 50µs is a common, well-proven value. ## Adjustable threshold — one part covers multiple rails Because the threshold is adjustable via external resistors, the MAX6459UTC+T is not locked to a single trip point. That reduces line-item count in the BOM when you need to supervise different supply voltages across board variants — same order code, different resistor divider. The open-drain output also allows wired-OR connection with other reset sources, which is handy in multi-rail systems where any one fault should trigger a system reset. ## Active production — no LTB risk The MAX6459UTC+T has an active lifecycle status and is ROHS3 compliant. There is no last-time-buy notice or obsolescence risk on the horizon. For new designs or production replenishment, this part is a safe choice without the sourcing headaches of a phase-out part.","metaTitle":"MAX6459UTC+T Simple Reset/Power-On Reset, SOT-23-6","metaDescription":"MAX6459UTC+T from Analog Devices is an active simple reset/power-on reset supervisor in SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"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":"50µs Typical","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Voltage - Threshold":"Adjustable/Selectable","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.92000","currency":"USD"},{"qty":10,"price":"$5.31200","currency":"USD"},{"qty":25,"price":"$5.02240","currency":"USD"},{"qty":100,"price":"$4.35260","currency":"USD"},{"qty":250,"price":"$4.12940","currency":"USD"},{"qty":500,"price":"$3.70528","currency":"USD"},{"qty":1000,"price":"$3.12494","currency":"USD"},{"qty":2500,"price":"$2.96869","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX6457-MAX6460.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout for MAX6459UTC+T?","answer":"The reset timeout is 50µs typical.
