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  
overcharged, an internal cell balancing network bleedsoff  
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.  
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  
VC pin. If one or both of the cells is determined to be  
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.
