... Li-ION CELL 0.1 F 0.1 F The NE57607 drives the series N-Channel MOSFETs to states determined by each of the cell’s voltage and the battery pack load current. During normal periods of operation, both the discharge and charge MOSFETs are in the ON state, thus allowing bidirectional current flow. ...

... The R-C filters around the NE57607 One needs to place R-C filters on the positive input pins of the NE57607. These are primarily to shield the IC from electrostatic occurrences and spikes on the terminals of the battery pack. A secondary need is during the occurrence of a short-circuit across the battery pack terminals ...
