Four-rail supervisor in a six-pin SOT
The MAX6339JUT is a multi-voltage supervisor from Analog Devices that monitors four independent supply rails in a single SOT-23-6 package.
Reset timing and output drive
A minimum reset timeout of 140 ms gives the downstream rail time to stabilize before the processor or FPGA is released from reset — long enough to cover most power-supply ramp profiles.
Industrial temperature and package fit
The SOT-23-6 package (supplier device package same as case) keeps the footprint small — useful when board space is tight and the supervisor sits near the monitored rails rather than at a central power-management IC.
