MITSUMI CMOS System Reset IC with Delay Time Circuit PST83XX, 84XX Series CMOS System Reset IC with Delay Time Circuit Monolithic IC PST83XX, 84XX Series May 21, 2009 Outline 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. Features 1. High accuracy 2. 3. 4. 5. 6.
