ADM6339 is a high accuracy supervisory circuit capable of monitoring up to four power supply voltages. It has 6 factory-set threshold options and adjustable input threshold options. It features low power consumption and glitch immunity.
The ADM6339 is a compact supervisory circuit that monitors up to four supply voltages. 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 adjustable thresholds (+1.23 V, +0.62 V, ‑0.5 V) for flexible system protection. Typical applications include telecommunications, microprocessor systems, data storage equipment, and servers/workstations.
Key features include a 200 ms typical reset timeout, open‑drain reset output with a weak internal pull‑up, low quiescent current (55 µA), glitch immunity, and operation over –40 °C to +85 °C. The device is supplied in a 6‑lead SOT‑23 package and meets absolute maximum ratings such as 20 mA continuous reset current.
