DESCRIPTION
The Si9730 monitors the charging and discharging of dual-cell
lithium-ion battery packs (carbon or coke chemistry) ensuring
that battery capacity is fully utilized while ensuring safe
operation. The Si9730 provides protection against
overcharge, over-discharge, and short circuit conditions which
are hazardous to the battery and the environment.
Battery voltages of each individual cell are monitored at the
center-tap connection by an internal A/D converter through the
V
C
pin. If one or both of the cells is determined to be
overcharged, an internal cell balancing network

current at 15 A until both cells are charged to the same
maximum level. Depending on the condition of each cell, the
Si9730 will switch two external source-connected n-channel
MOSFETs on or off to allow the cells to be charged or to
provide current to the load.
The Si9730 is available in an 8-pin SOIC package with an
operating temperature range of
25 to 85
°
C. The Si9730 is
available in both standard and lead (Pb)-free packages.
