The SY62510VXS is a fully integrated 1-series Lithium-ion/Li-Pol battery gauge with authentication. The device communicates via an I2C compatible interface and combines a low-power, high-speed micro-controller, integrated flash memory, peripherals and proprietary algorithm for accurate capacity gauging. The device is suitable for using on the host-side or can be integrated in battery packs.

The SY62510 provides the battery information such as: remaining battery capacity (mAh), state-of-charge (%, SOC), state-of-health (%, SOH), battery voltage (mV), battery current (mA) and battery temperature (℃).
