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 protec-
tion circuit monitors individual cell voltages to detect over-
voltage 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.
Features
? Complete Protection for 5-Cell to 10-Cell Li+ Packs
? Pin Programmable for 5 to 10 Cells
? Internal Cell-Balancing Circuit, Shunts Up to 300mA
? Pin-Programmable V OV Threshold
? Pin-Programmable Cell-Balance Voltage
? Overdischarge Current and Short-Circuit Current
