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 I²C 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.
