Order this document by MC33345/D MC33345 Product Preview 1 to 4 Cells Lithium Battery Safety IC 1 TO 4 CELLS LITHIUM The MC33345 is a Lithium Battery Safety Integrated Circuit designed to BATTERY SAFETY IC control the charge and discharge voltage safety limits of one to four lithium–ion or lithium polymer rechargeable cells. This device is designed to be placed inside the battery pack together with the cells and other external SEMICONDUCTOR components, to form a smart battery pack. Its main purpose is to ensure safe TECHNICAL DATA battery pack charging and discharging. The circuit also protects the integrity of the Li–ion cells. In effect, it avoids the degradation of the cells in case of overdischarge by causing the battery pack to go in a zero current SLEEPMODE? state. T
