Li-ion Battery Secondary Protection ICs

The R5640 in a MSOP-8 package is a suitable solution for battery packs with two to five cells. As for larger multi-cell battery packs with six cells or more, the R5640 has a control input (CTLC) and output pin (Cout) available for cascading multiple ICs. In this way, we are able to monitor battery packs with up to 10 or 15 cells for example.
