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.
* Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", "-" in the part number suffix describes RoHS status. Package drawings may show a different suffix character.
