The S-8229 Series is a battery monitoring IC developed using CMOS technology. Compared with conventional CMOS
voltage detectors, the S-8229 Series is ideal for the applications that require high-withstand voltage due to its maximum
operation voltage as high as 24 V.
The S-8229 Series is capable of confirming the voltage in stages since it detects three voltage values.
