AME8500 / 8501 µµµµµProcessor Supervisory is a microprocessor supervisor that automatically resets the CPU when the power supply voltage drops below the threshold. It features a wide range of voltage thresholds, reset time intervals, and output driver configurations, and has extremely low quiescent current. The device also includes a thermal shutdown function that shuts down the system when the ambient temperature exceeds 80°C.
The AME8500 and AME8501 are processor supervisory devices that provide customizable reset functions, voltage‑threshold selection, and output driver options. The AME8501 adds an over‑temperature shutdown feature. Both devices are offered in compact SOT‑23, SOT‑89 and SOT‑25 packages for portable, battery‑powered equipment.
The document includes functional descriptions, pin‑out tables, absolute maximum ratings, recommended operating conditions, thermal data, and a full ordering list with voltage options and package types. It also lists typical applications such as portable electronics, power supplies, and data‑acquisition systems.
