That is enough time for most oscillators to stabilise and for the core supply to settle before the CPU starts executing code. If your processor needs a longer reset pulse, you would need to add an external RC delay or switch to a supervisor with a programmable timeout — this part is fixed at 35ms. ## RoHS non-compliant — plan accordingly The MAX690TESA is marked RoHS non-compliant. That means it contains lead (Pb) above the RoHS exemption thresholds and cannot be used in new EU-market products without a RoHS exemption. For legacy repair, MRO, or military/aerospace builds where leaded solder is still accepted, this is not a blocker. If your BOM requires RoHS compliance, look at the MAX690TESA+ (the lead-free variant). ## Active production — no LTB risk The MAX690TESA is listed as Active with no last-time-buy or end-of-life notice. That means Maxim (now part of Analog Devices) continues to manufacture it, and the supply chain supports normal production orders. No urgency to stockpile or find a drop-in replacement for ongoing builds.","metaTitle":"MAX690TESA Battery Backup Circuit, 3.075V Threshold","metaDescription":"MAX690TESA battery backup supervisor IC with active-low push-pull reset, 35ms minimum timeout, 3.075V threshold, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Battery Backup Circuit","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"35ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.075V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.35","stockQuantity":0,"priceTiers":[{"qty":57,"price":"$5.35000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/88e1ca131f0f704acd25c3636243d3a9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout for MAX690TESA?","answer":"The reset timeout is a minimum of 35ms. After the monitored voltage rises above the 3.075V threshold, the reset output stays low for at least 35ms before releasing the processor."},{"question":"Does MAX690TESA have a watchdog timer?","answer":"No. The MAX690TESA is a battery backup circuit with reset only — it does not include a watchdog timer. The MAX691TESA is the sibling that adds a watchdog timer in the same pinout."},{"question":"MAX690TESA vs MAX691TESA: what is the difference?","answer":"Both are battery backup supervisors with a 3.075V threshold and active-low reset in an 8-SOIC package. The MAX691TESA adds a watchdog timer input (WDI) and a watchdog output (WDO) — the MAX690TESA omits those pins. If your design needs a watchdog, use the MAX691TESA; if not, the MAX690TESA is the simpler, lower-cost choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX690TESA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX690TESA when reusing this data.
