Dual-rail monitoring with a 140 ms hold
The MAX6715AUTLTD3+T: When either rail drops below its threshold, the active-low open-drain output asserts reset and holds it for a minimum of 140 ms after all rails return above threshold — long enough for the downstream processor's oscillator and PLL to lock before the core starts executing code.
Housed in a 6-lead SOT-23 package (SOT-6 supplier device package), it mounts on standard surface-mount pads with a 0.95 mm pitch — a straightforward hand-solder or reflow profile compatible with lead-free assembly.
