The DS2726 provides full charge and discharge protection for 5- to 10-cell lithium-ion (Li+) battery packs. The protection circuit monitors individual cell voltages to detect overvoltage and undervoltage conditions. Protection against discharge overcurrent and short-circuit current is provided with user-selectable thresholds using external resistors. P-channel protection FETs are employed high side and driven from on-chip 10V FET drivers. Cell balancing can be enabled to ensure that all cells are equally charged.

An evaluation kit is available: DS2726EVKIT
