DS2760 lithium-ion battery protection circuit

Published:2011/9/12 22:04:00 Author:John | Keyword: lithium-ion battery | From:SeekIC

DS2760 has a 25mΩ sense resistor inside, which can detect two-way (charging and discharging) current (but its resistance and loss are bothe extremely small). The current resolution is 0.625mA and the dynamic range is within l.8A. It isalso with current cumulative function. The voltage measurement resolution is 48mV. Its temperature measurement resolution is up to 0.125 ℃. The digital converted by the A / D converter is stored in the corresponding memory container. It is connected with the main system through a single interface, thus leading it to be able to do management and control on lithium-ion battery power supply. Therefore, it is able to read / write access and control with internal memory container.
