The open-drain output allows wired-OR connection with other reset sources, and the pull-up resistor is external — choose a value that keeps the rise time within the processor's reset input spec. ## Nanopower quiescent — why the series name matters for battery life The nanopower series is built for always-on monitoring where the supervisor's own draw must not compete with the system's sleep current. Typical quiescent current for the nanopower family is in the sub-1 µA range — the exact figure for this variant is in the datasheet, but the series branding signals that the part is optimised for battery-powered or energy-harvesting designs where every microamp counts. ## SOT-23-5 footprint and sourcing posture Housed in the standard SOT-23-5 (SC-74A) package, the MAX6866UK26D3L+ shares the same 5-pin footprint as many other supervisory ICs — the layout is straightforward and the part is a drop-in for existing designs that use a 2.625V threshold supervisor in this package.","metaTitle":"MAX6866UK26D3L+ Simple Reset/Power-On Reset","metaDescription":"MAX6866UK26D3L+ nanopower reset IC from Analog Devices, active-low open-drain output, 2.625V threshold, 150ms timeout, -40 to +85°C.
