Two-rail supervisor in a SOT-23-8
The MAX6705ARKA+ is a dual-voltage power supply monitor from Analog Devices that tracks two independent rails and asserts a common active-low reset when either drops below its threshold.
Reset timing and temperature range
The reset timeout is 120ms minimum — long enough to let the downstream supply and oscillator settle after a brown-out event, but short enough that a 200ms power-cycle brings the system back within the host watchdog window.
SOT-23-8 package and board-fit
Housed in a standard SOT-23-8 surface-mount package, the MAX6705ARKA+ shares the same 0.65mm pitch and 2.9mm × 1.6mm footprint as other common supervisors — the layout is interchangeable with many pin-compatible parts in the same family. The bulk packaging means it ships in tubes or trays rather than tape-and-reel — factor this into your pick-and-place setup if the line expects reel-fed parts.
