Figure 4. Cell Bypassing Connection
Configuration for Number of Cells
The DS2726 protects 5 to 10 Li+-based cells connect-
ed in series. The number of cells is configured using
the SEL0 and SEL1 pins according to Table 2.
Pin V10 should always be connected to the positive ter-
minal of the battery stack regardless of the number of
cells in the stack. Cell connections that are not in use
for battery stacks with fewer than 10 cells should be
shorted to the cell connection below it. For example, a
stack with 9 cells would have V9 shorted to V8 and V8
Table 2. Number of Cells Configuration
connected to the positive terminal of the 8th cell; a
stack with 8 cells would have V9 shorted to V8 shorted
to V7 and V7 connected to the positive terminal of the
7th cell, and so on (see Figure 4).
Cell Connection Order
Care must be taken when connecting cells to the
DS2726 to avoid damaging the device. GND should be
connected first, then V IN . Next, V0 should be connect-
ed, then V1 and so on until V10 is connected last.
