BMA7418 is an automotive lithium-ion (Li-ion) battery cell controller-integrated circuit (IC) with a dedicated, high-accuracy analog-to-digital converter (ADC) per voltage measurement channel. Electrochemical impedance spectroscopy (EIS) is supported by a high synchronization capability and integrated Discrete Fourier Transform (DFT) per measurement channel. A product family approach — where products are pin compatible and use the same software — you can exchange BMA7118 and BMA7418 at low effort. BMA7418 offers low 5 mA current consumption due to its integrated DC-to-DC converter. As a fully redundant and independent internal architecture, it achieves automotive safety integrity level (ASIL) D functional safety.
