Two-rail supervisor in a six-pin SOT
The MAX6360SYUT-T: When either rail drops below its threshold, the active-low reset output (push-pull, totem-pole) pulls low and holds for a minimum of 100ms after both rails recover. This is the supervisor you reach for when a dual-supply processor or FPGA core needs a clean power-good handshake at 1.8V and 2.5V or 3.3V and 1.2V — the two thresholds bracket those common logic voltages.
Thresholds and reset timing for the BOM
The 2.19V threshold monitors a nominal 2.5V or 1.8V rail; the 2.93V threshold watches a 3.3V rail. When either falls below its threshold, the active-low reset asserts — no sequencing, no external capacitor to set timing. The 100ms minimum reset timeout gives downstream logic time to stabilize before the supervisor releases the reset line. The SOT-23-6 package keeps the footprint small — six pins, one for each monitored input, ground, reset output, and supply. No exposed pad, so the board layout is straightforward.
