It asserts both active-high and active-low push-pull reset outputs for a minimum of 140 ms after the supply rises above the threshold, holding downstream logic in reset until the rail stabilizes. ## 140 ms minimum reset timeout — what it buys you ## Dual reset outputs — one part, two polarities Active-high and active-low push-pull outputs on the same die mean this single supervisor can drive both an MCU reset pin (active-low) and a peripheral enable (active-high) without an external inverter. Both outputs are asserted during the timeout and de-asserted together when the timeout expires. No open-drain pull-up resistors needed — the push-pull stage drives rail-to-rail. The 8-SOIC package keeps board area small while offering enough pin pitch for manual rework or inspection. The part is RoHS non-compliant, which may matter for EU RoHS-exempt applications or legacy BOMs where lead-bearing solder is still accepted.","metaTitle":"MAX814LESA Simple Reset/Power-On Reset IC, 140ms","metaDescription":"MAX814LESA Simple Reset/Power-On Reset IC from Maxim Integrated. 140ms minimum reset timeout, 4.7V threshold, dual active-high/active-low outputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active High/Active Low","Output":"Push-Pull, Push-Pull","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.7V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.3","priceTiers":[{"qty":37,"price":"$8.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/47879c97dd62a9ba599c66deebb07f03.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX814LESA/alternatives.json"},"ai":{"faq":[{"question":"What is the exact reset timeout of MAX814LESA?","answer":"The reset timeout is 140 ms minimum. This is the guaranteed hold time the reset outputs stay asserted after the monitored voltage rises above the 4.7 V threshold."},{"question":"Can MAX814LESA be used as a direct replacement for MAX813L?","answer":"The MAX813L is a different supervisor with a 4.65 V threshold and a 200 ms timeout. The MAX814LESA uses a 4.7 V threshold and a 140 ms timeout. Verify your system's threshold tolerance and reset hold time requirements before substituting — the pinout may differ, and the timing change could affect power-up sequencing."},{"question":"Is MAX814LESA compatible with 3.3 V systems?","answer":"No — the threshold voltage is 4.7 V, designed for monitoring 5 V rails. For 3.3 V systems, select a supervisor with a threshold near 3.0 V or 3.1 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX814LESA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX814LESA when reusing this data.
