4.6V threshold, 30µs timeout — what the numbers mean for fit
The MAX6806US46-T: The 4.6V threshold is the voltage at which the reset asserts when the monitored rail drops below that level. For a 5V supply rail, this threshold sits roughly 8% below nominal — typical for supervisor ICs that need to catch a brownout before the downstream logic enters an undefined state. The 30µs typical reset timeout holds the reset output low for that duration after the rail recovers, giving the supply and oscillator time to stabilize before the processor starts executing code. The 8-µMAX package is a 3mm-wide MSOP footprint — a space-efficient choice for densely populated boards where a larger SOIC would crowd adjacent passives.
