18 Cells Analog Front End IC with SPI interface - Tray

The BMA7118 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 with high synchronization capability—a requirement for electrochemical impedance spectroscopy (EIS).

Upgrading to EIS is lower in cost, due to pin compatibility and shared software across the product family. BMA7118 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.
