Maxim has introduced the DS2741 current monitor/accumulator for cost-sensitive, lithium-ion (Li+) applications. Incorporating a high-side current-sense resistor, this 3 x 3 mm device allows users to connect it directly to the power source to detect downstream failures and trigger appropriate corrective action. Additionally, it avoids the ground disturbance associated with low-side current-sense designs. The device manages to provide a complete current sensing, measuring and accumulation solution tailored for battery charge control and remaining capacity estimation 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°C to +70°C operating range with a resolution of ±1°C. The device consumes 60 μA during active operation and only 1 μA in low-power sleep mode.
