DS2741 Current Monitor and Accumulator with Integrated Sense Resistor
DS2741概述
The DS2741 current monitor/accumulator is a complete current-sensing, measuring, and accumulation device tailored for cost-sensitive, battery-powered applications in a small 3mm x 3mm TDFN package. As a result, the DS2741 is a key component in battery-charge control and remaining capacity-estimation applications.
Through its I²C interface, the DS2741 gives the host system access to current measurement and accumulation registers. The 7-bit slave address is factory programmable, allowing up to 128 devices to be individually addressed by the host system.
