Key Featrues
Extended Manual Reset Setup Period: The MAX6443–MAX6452 series features a long manual reset setup period, which ensures that short switch closures (nuisance resets) are ignored. This enhances reliability in applications where accidental resets could disrupt operations, such as in automotive or industrial equipment.
Low Supply Current: With a supply current of just 6µA, these supervisory circuits minimize power consumption, making them ideal for battery-powered devices like MP3 players, medical devices, and other portable electronics, where energy efficiency is critical.
Precision Factory-Set Reset Thresholds: The devices offer precision reset thresholds ranging from 1.6V to 4.6V, ensuring accurate voltage monitoring and reliable system resets. This precision is particularly beneficial in consumer electronics and set-top boxes, where consistent performance is essential.
Immune to Short Voltage Transients: The circuits are designed to ignore short voltage transients, preventing false resets caused by power fluctuations. This feature improves system stability in environments with noisy power supplies, such as industrial equipment or automotive systems.
Small SOT143 and SOT23 Packages: The compact package sizes (SOT143 and SOT23) allow for space-efficient designs, making these supervisory circuits suitable for applications with limited board space, such as cable/DSL modems, DVD players, and other compact consumer electronics.
