This document is the product manual of Analog Devices, introduces the function and features of ADM6384 microprocessor supervisory circuit, including precision power supply monitoring, 31 reset threshold options, four reset timeouts, manual reset input, reset output stage, guaranteed reset output valid to VCC = 1 V, power supply glitch immunity, specified over the −40°C to +125°C temperature range, 4-lead SC70 package, etc.
The ADM6384 monitors power‑supply voltage levels in microprocessor‑based systems and generates a reset when the voltage falls below a programmable threshold. It offers 31 threshold options from 1.58 V to 5.0 V, four reset timeout periods (1 ms, 20 ms, 140 ms, 1120 ms), a manual reset input, and a push‑pull active‑low reset output that remains valid down to VCC = 1 V.
Designed for low‑power, portable equipment, the device consumes only a few picoamps of supply current and is supplied in a 4‑lead SC70 package that operates from –40 °C to +125 °C. The datasheet provides detailed specifications, pin functions, typical performance curves, and ordering information.
