CMOS System Reset IC with Delay Time Circuit PST83XX, 84XX Series

CMOS System Reset IC with Delay Time Circuit

Monolithic IC PST83XX, 84XX Series

Outline

May 21, 2009

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.
