The S-8229A 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.

*1. −VDETtotal: Total detection voltage
−VDETtotal = −VDET1(S) + −VDET2(S) + −VDET3(S)
*2. Full charge all on: When the input voltage is equal to or higher than each of the three detection voltage values,
VOUT1 = VOUT2 = VOUT3 = VSS.
Full charge all off: When the input voltage is equal to or higher than each of the three detection voltage values,
VOUT1 = VOUT2 = VOUT3 = “High-Z”.
