The BMA7424 and BMA7426 are automotive lithium-ion battery cell controllers (BCCs) integrated circuits (ICs) supporting 24 and 26 cells, respectively. They feature high-accuracy, highly synchronized analog-to-digital controllers (ADCs) on each voltage channel and integrate a discrete fourier transform (DFT) engine for electrochemical impedance spectroscopy (EIS). They offer pin compatibility and a shared software platform with non-EIS variants enabling a cost-effective EIS implementation. They consume only 4 mA (typ.) and support ASIL D functional safety.
