When the supply drops below that level, it pulls its open-drain output low and holds it there for a minimum of 250ms after the rail recovers — enough time for most microcontrollers and SoCs to finish their power-on reset sequence. The open-drain output lets you wire-OR it with other reset sources or level-shift to a lower-voltage logic input with a pull-up resistor. ## 4.625V threshold — why that number matters A 4.625V trip point is typical for 5V nominal systems where the processor or logic needs to see a valid supply before releasing reset. If your design runs from a 5V rail that sags under load (say a motor start or a radio burst), this part holds the processor in reset until the rail is back above the threshold plus the hysteresis. The 250ms timeout gives the oscillator and PLL time to stabilize before the first instruction fetch. For 3.3V or 1.8V cores, you would want a different threshold variant in the DS1233 family. ## Package and temperature range for the environment Housed in a surface-mount SOT-223-3 package (TO-261-4 equivalent), this part fits standard reflow profiles and takes up minimal board space. The -40°C to 85°C operating range covers industrial environments — outdoor telecom cabinets, factory-floor controllers, and automotive cabin applications. No AEC-Q grade is listed, so it is not qualified for under-hood or powertrain domains. ## Lifecycle and sourcing posture The DS1233DZ-5+ carries an Active lifecycle status and is ROHS3 compliant. For BOM planning, this means no near-term obsolescence risk and no need to qualify a substitute.","metaTitle":"DS1233DZ-5+ Simple Reset/Power-On Reset, 4.625V Threshold","metaDescription":"Maxim DS1233DZ-5+ EconoReset supervisor: active-low open-drain output, 250ms timeout, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"EconoReset","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"EconoReset","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"250ms Minimum","Package / Case":"TO-261-4, TO-261AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.625V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-223-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.94","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.94000","currency":"USD"},{"qty":10,"price":"$2.64400","currency":"USD"},{"qty":25,"price":"$2.49960","currency":"USD"},{"qty":100,"price":"$2.16640","currency":"USD"},{"qty":250,"price":"$2.05536","currency":"USD"},{"qty":500,"price":"$1.84426","currency":"USD"},{"qty":1000,"price":"$1.55540","currency":"USD"},{"qty":2500,"price":"$1.47763","currency":"USD"},{"qty":5000,"price":"$1.42208","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/DS1233D.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS1233DZ-5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS1233DZ-5 when reusing this data.
