What the 2.93V threshold means for your rail
The MAX6386LT29D3+T: That 2.93V threshold sits just above the typical 2.5V or 2.8V core supply of many MCUs and FPGAs — so the supervisor catches a brownout before the digital logic starts seeing undefined states, then gives the rail a full 140ms to stabilise before releasing the reset.
Active low, open drain — wiring it into a system
This lets you wire-OR the reset line with other supervisors or a manual reset button — just add a pull-up resistor to the logic supply.
Temperature range and package for real hardware
The 6-WFDFN package (1.5mm x 1.0mm, 0.5mm pitch) is a tiny no-lead footprint that saves board space but demands careful solder-paste stencil design to avoid bridging on the exposed pad.
