NXP Cmmunicatr Intrducing NXP s MC33771B MC33771B: 14-Channel Li-in Battery Cell Cntrller IC and NXP Semicnductrs, High Tech Campus 60, 5656 AG Eindhven, the Netherlands www.nxp.cm
1 Prduct Summary The 33771B is a SMARTMOS lithium-in battery cell cntrller IC designed fr autmtive applicatins, such as hybrid electric (HEV) and electric vehicles (EV) alng with industrial applicatins, such as energy strage systems (ESS) and uninterruptible pwer supply (UPS) systems. The device perfrms ADC cnversins f the differential cell vltages and current, as well as battery culmb cunting and battery temperature measurements. The infrmatin is digitally transmitted thrugh the SPI r transfrmer islatin t a micrcntrller fr prcessing.
