Overview
DS2726 19-5482; Rev 3; 8/10 5-Cell to 10-Cell Li+ Protector with Cell Balancing General Description 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.
