Three-channel voltage supervisor for multi-rail sequencing
The MAX6701SKA-T is a three-channel power supply monitor from Analog Devices that supervises up to three voltage rails with a fixed 2.93 V threshold on one channel and two adjustable thresholds on the others. Its active-low reset output (push-pull, totem pole) asserts when any monitored rail falls below its threshold and holds for a minimum 120 ms after all rails return to tolerance, giving downstream logic time to stabilize.
Threshold configurability and temperature range
The fixed threshold of 2.93 V suits a 3.3 V rail, while the two adjustable inputs let the designer set undervoltage limits for other supplies using external resistor dividers — typical for multi-voltage systems like FPGAs or SoCs that sequence core, I/O, and auxiliary rails. The SOT-23-8 package keeps the footprint small — suitable for space-constrained designs where a supervisor must sit close to the monitored rail's load.
Lifecycle and sourcing posture
It is listed as RoHS non-compliant, which may affect procurement for designs requiring full RoHS conformance — verify against your own compliance requirements.
