SY24561 Datasheet | Silergy

Cost-saving single Li-lon Battery Gauge General Description The SY24561 is a cost-save gauge IC for single cell lithium-ion (Li+) battery in handheld and portable equipments. The SY24561 senses battery terminal voltage and adopts the proprietary algorithm to calculate the corresponding state of charge (SOC). paring with conventional voltage-based gauge which translates terminal voltage to SOC directly, the sophisticated algorithm in the SY24561 shows great advantage in SOC accuracy. The SY24561 can be classified as advanced voltage-based gauge which does not need current sensors and the SOC accuracy will not diverge with time. SOC and voltage information is accessed by the I2C interface. The SY24561 is available in DFN2×2-8.
