The push-pull, totem-pole output drives the reset input of an MCU or logic device directly without an external pull-up resistor. The 140ms minimum reset timeout holds the processor in reset long enough for the supply and oscillator to stabilise after a brownout or power-up event — a standard supervisory window for most 8- and 32-bit microcontrollers. It is not qualified for automotive or extended industrial environments where -40°C to +85°C or +125°C is required. ROHS3 compliant per the lifecycle record, with no restricted-substance exemptions — no additional paperwork needed for EU or California market shipments.","metaTitle":"MAX815KCSA+ Simple Reset Supervisor, 4.8V Threshold, 8-SOIC","metaDescription":"MAX815KCSA+ active supervisor IC, 4.8V threshold, 140ms reset timeout, push-pull output, 8-SOIC.

This is the guaranteed pulse width the part asserts after the supply voltage rises above the 4.8V threshold, giving the downstream processor time to complete its power-on reset sequence."},{"question":"Can MAX815KCSA+ be used in a 5V system with a 4.8V threshold?","answer":"Yes — the 4.8V threshold is designed for a nominal 5V supply rail. It asserts reset when the rail drops to 4.8V, which is approximately 4% below the nominal 5V level, providing early warning before the logic supply falls out of regulation."},{"question":"Is MAX815KCSA+ RoHS compliant?","answer":"Yes, it is ROHS3 compliant — the highest level of RoHS compliance, covering all ten restricted substances including the four phthalates added in EU RoHS 2015/863."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX815KCSA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX815KCSA when reusing this data.
