IC for CMOS System Reset PST81XX, 82XX Series
IC for CMOS System Reset
Monolithic IC PST81XX, 82XX Series
Outline
This IC functions in a variety of CPU systems and other logic systems, to detect supply voltage and reset the system
accurately when the power is turned on or interrupted.
To ±1.5% of detection voltage accuracy of the conventional models, a maximum of ±0.5% of super-high precision
is realized, and it is more suitable for battery detection etc. Moreover, the mounting area significantly contributes to
space saving using the SSON package.
