AME8500 / 8501 µµµµµProcessor Supervisory is a micro-processor supervisory device produced by AME company, which has 11 voltage threshold options, 5 reset interval options, 4 output configuration options, wide temperature range, low temperature coefficient, low quiescent current and thermal shutdown option.
The AME8500/8501 family provides customizable processor supervisory functions, allowing users to set reset voltage thresholds, reset time intervals, and output driver configurations without external components. The devices monitor supply voltage and assert a reset when the voltage drops below a programmed threshold, with optional over‑temperature shutdown in the AME8501 variant.
Available in compact SOT‑23, SOT‑89 and SOT‑25 packages, the parts offer low quiescent current (<3 µA) and operate over a wide temperature range (‑40 °C to 85 °C). The datasheet includes detailed pin descriptions, ordering tables, absolute maximum ratings, recommended operating conditions, and thermal information.
