Four-rail supervision in a 4x4 TQFN
The MAX16001DTE+ is a multi-voltage supervisor from Analog Devices that monitors four supply rails with a single IC. The active-low reset output is open-drain, so multiple supervisors can wire-OR their reset signals to a common pull-up without contention. The reset timeout is adjustable via an external capacitor, which lets you tune the power-on delay to match the downstream processor's startup sequence.
Temperature grade and package fit
The 16-TQFN (4x4) package has an exposed pad that must be soldered to a PCB thermal land — the datasheet's recommended footprint ties the pad to the ground plane for heat sinking.
