Complete lithium-ion Battery Monitor in 3mm x 3mm Package

Additionally, it avoids the ground disturbance associated with low-side, current-sense designs. The DS2741 provides a complete current-sensing, measuring, and accumulation solution tailored for battery-charge-control and remaining-capacity-estimation applications. The device is ideal for handheld wireless products such as multimedia players, mobile phones, PDAs, and digital cameras. It is also well suited for automotive/telematics applications.



In order to support adjustments to battery-capacity estimates based on temperature, the DS2741 integrates a temperature sensor that measures temperatures over the entire -20 degrees Celsius to +70 degrees Celsius operating range with a resolution of ±1 degree Celsius.



The device consumes 60microamps (typ) during active operation and only 1microamp (typ) in low-power sleep mode, which increases battery runtime by minimizing drain on the battery.
