TECHNICAL DATA
CMOS System Reset IC with Delay Time Circuit Monolithic IC KIC72** Series
In various CPU systems or other logic systems, when the time of a power suply injection and a power supply are severed for a momnet, this IC detects supply voltage and applies reset to a system. To 2% of detection voltage accuracy of the conventional product, a maximum of 1% of super-high precision is realized, and it is more suitable for battery detection ets.
