MC33772C Description
The MC33772C is a SMARTMOS lithium-ion battery cell controller IC designed for automotive applications, such as hybrid electric (HEV) and electric vehicles (EV) along with industrial applications, such as energy storage systems (ESS) and uninterruptible power supply (UPS) systems. The device performs ADC conversions of the differential cell voltages and current, as well as battery coulomb counting and battery...
