Four-rail supervision in a SOT-23-6
The MAX6710BUT: Factory-programmed thresholds at 2.32 V, 3.08 V, and 4.63 V cover common logic and I/O voltages, plus an adjustable input for a fourth rail set by an external resistor divider. When any monitored voltage drops below its threshold, the open-drain output pulls low and holds for a minimum 140 ms reset timeout after all rails recover, ensuring the downstream processor sees a clean power-good signal.
Where this supervisor fits on the board
Surface-mount SOT-23-6 footprint — the same land pattern as a standard SOT-23-5 with an extra pin, so the layout is straightforward on a two-layer board. Active-low reset with open-drain output lets multiple supervisors share a common pull-up resistor and wire-OR their reset signals — useful when sequencing several power domains.
