DS2780E+

Battery Management Overview

The DS2780E+ is a standalone fuel gauge integrated circuit designed for single-cell lithium-ion and lithium-polymer batteries. It operates within a supply voltage range of 2.5 V to 5.5 V, with a maximum output voltage of 5.5 V. The device functions reliably across an extended temperature range from -40°C to +85°C while consuming a typical operating current of 65 µA. Packaged in an 8-TSSOP surface-mount format, it utilizes the I2C interface for communication. This component serves as a dedicated battery management solution for portable electronics requiring accurate state-of-charge monitoring.
