Reset is active low, so it connects directly to the /RESET pin on most MCUs and MPUs. Packaged in a 5-pin SOT-23-5, it is a surface-mount part. The operating temperature range of -40°C to 85°C covers industrial environments. ## 4.625V threshold — why that number matters The 150ms minimum reset timeout ensures the supply has fully ramped and oscillated before the processor releases. For systems with large bulk capacitance or slow-start supplies, this is enough to avoid spurious resets on power-up. ## Active lifecycle — no LTB pressure It's a current-design part, suitable for new BOMs and production runs without obsolescence risk. RoHS non-compliant (lead-bearing finish). Verify your assembly house can accept SnPb solder processes before committing the BOM.","metaTitle":"MAX6865UK46D3S Simple Reset/Power-On Reset IC","metaDescription":"MAX6865UK46D3S is a Simple Reset/Power-On Reset IC with active-low push-pull output, 4.625V threshold, 150ms timeout, SOT-23-5.

The MAX6865 uses a push-pull output; the MAX6864 uses an open-drain output. If your design requires an open-drain reset line (e.g., shared reset bus with pull-up), the MAX6865 will not work without a buffer."},{"question":"Does MAX6865UK46D3S have an open-drain output?","answer":"No. The output is push-pull, totem pole. It drives the reset line high or low without needing an external pull-up resistor. If you need an open-drain output, look at the MAX6864UK46D3S."},{"question":"Can MAX6865UK46D3S be used in 5V systems?","answer":"Yes. The 4.625V threshold is specifically designed for 5V rails. It asserts reset before the supply drops below the safe operating range of 5V logic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6865UK46D3S","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6865UK46D3S when reusing this data.
