Automotive qualified ASIC for battery control applications

Automotive qualified ASIC for battery control applications

The IC permanently measures battery voltage, battery current, battery temperature and battery lifetime to compute the State-Of-Charge (SOC) and the State-Of-Health (SOH) of batteries. The ASIC targets applications such as high-voltage battery systems (Li-Ion) for vehicles (trains, cars, motorbikes, …) as well as Lead-Acid battery systems (12V, 24V and 42V). This ASIC is a general purpose platform for battery control applications.
