The 125°C upper limit allows placement near a hot processor or power module without derating concerns. ## Output type and what it demands from your board The reset output is active-low, open-drain. That means the output pin pulls to ground when reset is asserted, and floats when reset is released. You must provide an external pull-up resistor to the logic supply (typically 10kΩ to 100kΩ) to get a valid high level. The open-drain topology is useful because it lets you wire-OR the reset signal with other supervisors or a manual reset button — any device pulling the line low forces a system reset. It also means the output voltage is not limited by the supervisor's supply; you can pull up to a different voltage rail if the downstream logic requires it. ## Package and footprint reality Housed in a SOT-143-4 package, this is a four-pin surface-mount part with a 1.4mm pitch. The SOT-143 footprint is common and well-supported in assembly houses. No exotic handling required — this is a straightforward reflow-solder part. ## Lifecycle and sourcing posture There is no end-of-life notice, no last-time-buy window, and no forced migration risk for new designs. ROHS3 compliant per the manufacturer's declaration. Because the part is active, lead times typically track with standard semiconductor supply — no special broker sourcing required, but the independent channel gives flexibility for urgent or non-standard quantity requests.","metaTitle":"MAX6315US44D2+T Simple Reset/Power-On Reset, 4.39V Threshold","metaDescription":"MAX6315US44D2+T is an active simple reset/power-on reset IC from Analog Devices.

For a 3.3V rail, a part with a threshold near 2.93V or 3.08V would be the functional equivalent in the same footprint.

In a 3.3V system, the supply never reaches 4.39V, so the supervisor would hold the reset line asserted indefinitely. For 3.3V systems, select a supervisor with a threshold in the 2.6V to 3.1V range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6315US44D2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6315US44D2T when reusing this data.
