Three-rail supervisor in a SOT-23-6 — what it covers
The open-drain output allows wired-OR connection with other supervisors or a system power-good bus.
Thresholds and reset timing — fit for the BOM
The fixed 1.313 V threshold suits low-voltage core rails, while the 2.188 V threshold matches I/O supplies. The adjustable channel handles any remaining rail via two resistors.
The part is RoHS non-compliant per the original release, which matters for builds that must meet RoHS directives — verify your exemption or plan for a compliant alternate if needed.
