DS2720 Efficient, Addressable Single-Cell Rechargeable Lithium Protection IC

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. Additionally, the command set supports a means of performing simultaneous switching of multiple battery packs, allowing the DS2720 to function as a battery selector in these applications.
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, supporting multibattery operation.
Two types of user-memory are provided on the DS2720 for battery information storage: EEPROM and lockable EEPROM EEPROM memory saves important battery data in true nonvolatile (NV) memory that is unaffected by severe battery depletion, accidental shorts, or ESD events. Lockable EEPROM becomes ROM when locked to provide additional security for unchanging battery data.
