Automotive Battery Management ICs

ST's automotive offer for Battery Management Systems (BMS) includes highly-integrated chips able to provide the highest accuracy measurements for cell monitoring. Our portfolio meets the stringent Automotive Safety Integrity Level (ASIL) D compliance.

Whether for mono or bi-directional daisy-chain configurations, our automotive battery management ICs integrate sophisticated features to accurately verify the state-of-charge (SoC) of lithium-ion batteries. Advanced diagnostic features also allow to monitor the system's state of health (SoH) during charging and discharging operations.
