The ADM6339 is a high accuracy supervisory circuit capable of monitoring up to four power supply voltages.
The ADM6339 monitors up to four power‑supply voltages and provides an open‑drain reset output that stays low for a typical 200 ms timeout. It offers six factory‑set threshold options (‑5.0 V, +1.8 V, +2.5 V, +3.0 V, +3.3 V, +5.0 V) and three user‑adjustable thresholds (+1.23 V, +0.62 V, ‑0.5 V).
Designed for telecommunications, microprocessor systems, data‑storage equipment and servers, the device is supplied in a 6‑lead SOT‑23 package, operates from –40 °C to +85 °C and draws only 55 µA typical current.
