... Philips Semiconductors Li-ion battery charger control with adjustable thresholds DESCRIPTION The NE57610 is a one- or two-cell, Li-ion battery charger controller which includes: constant-current and constant-voltage charging, a precise charge termination, pre-charging of undervoltage cells, overcharge timer, and under- and over-temperature detection. The NE57610 is available in the very small TSOP-24A package. ...

... Lithium cells must be charged with a dedicated charging controller such as the NE57610. The charging ICs, in general, can be described as performing: a current-limited, constant-voltage charge process. When the cell is very discharged, the charger IC outputs a constant current into the battery, which limits the internal heating of the cells ...

... Philips Semiconductors Li-ion battery charger control with adjustable thresholds NE57610 OPERATION The typical application schematic is given in Figure 17. Because in a multiple-cell battery pack, the battery charger cannot access the connection(s) between the cells within a battery pack, the following discussion is based upon the calculated value of each cell’s voltage (V /number of series cells) ...
