DS2770 is a battery fuel gauge and lithium-based and nickel-based chemical battery charger control integrated chip produced by Dallas Semiconductor. It can communicate with the power management system through the Dallas-Wire interface. , to read detection information such as battery voltage and temperature, and to read and write E2PROM at the same time, so it can be widely used in portable electronic devices. The unregulated power supply pulse charger based on DS2770 is shown in the figure below.
