DESCRIPTION  
The DS2720 single-cell rechargeable Li+ protection IC provides electronic safety functions required for  
rechargeable Li+ applications including protecting the battery during charge, protection of the circuit  
from damage during periods of excess current flow and maximization of battery life by limiting the level  
of cell depletion. Protection is facilitated by electronically disconnecting the charge and discharge  
conduction path with switching devices such as low-cost N-channel power MOSFETs.  
Since the DS2720 provides high-side drive to external N-channel protection MOSFETs from a 9V charge  
pump, superior on-resistance performance results compared to common low-side protector circuits using  
the same FETs. The FET on-resistance actually decreases as the battery discharges.  
Adding to the uniqueness of the DS2720 is the ability of the system to control the FETs from either the  
data interface or a dedicated input thereby eliminating the power-switch control redundancy of  
rechargeable Li+ battery systems.  
Through its 1-Wire interface, the DS2720 gives the host system read/write access to status and control  
registers, instrumentation registers, and general-purpose data storage. Each device has a factory-  
programmed 64-bit net address that allows it to be individually addressed by the host system.  
1-Wire is a registered trademark of Dallas Semiconductor.
