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.
