The AME8500 family from AME, Inc. is a processor supervisory designed for μP based systems. It features multiple voltage threshold options, tight voltage threshold tolerance, various reset time interval options, and different output configuration options. Additionally, the AME8501 also includes overtemperature shutdown functionality.
The AME8500 family offers user‑selectable reset voltage thresholds, reset time intervals, and output driver configurations, all preset at the factory. The devices monitor supply voltage and assert a reset when the voltage drops below the set threshold, with optional active‑high or active‑low outputs and push‑pull or open‑drain drivers. The AME8501 adds an over‑temperature shutdown that triggers at 80 °C and releases at 60 °C.
Available in small SOT‑23, SOT‑89 and SOT‑25 packages, the devices feature low quiescent current (< 3 µA) and a wide operating temperature range (‑40 °C to +85 °C). Detailed ordering information, pin configurations, absolute maximum ratings, and mechanical dimensions are provided for system designers.
