DS2745U+T&R
电池管理 I2C Battery Monitor Fuel Gauge
Low-Cost I2C Battery Monitor
DESCRIPTION
The DS2745U provides current-flow, voltage, and temperature measurement data to support batterycapacity 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 I2 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.
