Overview
In various CPU systems or other logic systems, when the time of a power supply injection and a power supply are severed for a moment, this IC detects supply voltage and applies reset to a system.
To ±1.5% of detection voltage accuracy of the conventional product, a maximum of ±0.5% of super-high precision is realized, and it is more suitable for battery detection etc.
The accuracy from elegance is conventionally raised from +100/-50% to ±10% also about delay resistance.
Moreover, the component-side product is realizing the small space using SSON-4.
Application
・Reset circuits for microcomputers, CPUs and MPUs
・Reset circuits for logic circuits
・Battery voltage check circuits
・Back-up power supply switching circuits
・Level detection circuits
