DESCRIPTION
The DS2441 1-Cell Li-Ion Battery Manager provides all essential functions for monitoring, protecting
and managing one-cell lithium-ion battery packs. The DS2441 constantly measures cell voltage, current,
and temperature, and automatically takes action to disable charging and/or discharging of the cell to
protect it when undesirable conditions arise.
Via its 1-Wire interface, the DS2441 provides the host system access to identification information, status
data, configuration and control settings, instrumentation registers, and general purpose data storage. Each
DS2441 has a factory-programmed 64-bit ROM ID which allows the host system to verify the
authenticity of the battery pack as well as a factory-programmed 16-bit manufacturing ID which can be
used to encode assembly location, cell chemistry and other information. A full set of status information
in the DS2441 keeps the host informed about protection conditions, remaining capacity and other matters.
Configuration and control fields in the device allow the host to disable charging and/or discharging, put
the battery pack in a low-power mode, and set various timing parameters. In addition, instrumentation
