DESCRIPTION
The DS2745 provides current-flow, voltage, and
temperature measurement data to support battery-
capacity monitoring in cost-sensitive applications. The
DS2745 can be mounted on either the host side or
pack side of the application. Current measurement
and coulomb counting is accomplished by monitoring
the voltage drop across an external sense resistor,
voltage measurement is accomplished through a
separate voltage-sense input, and temperature
measurement takes place on-chip. A standard I 2 C
interface with software programmable address gives
the controlling microprocessor access to all data and
status registers inside the DS2745. A low-power sleep
mode state conserves energy when the cell pack is in
storage.
