KA49702A

KA49702A are 1-chip battery monitoring IC for Li-ion battery cells, which have built-in high-resolution ADCs and can measure the voltage and current levels of battery cells with high accuracy. The IC can support applications with up to 17 battery cells connected in series or applications with a maximum voltage of 85V, contributing to the miniaturization of battery management systems. KA49702A achieves a voltage measurement accuracy +/-2.9mV, the highest standard in the industry. Additionally, the IC can support a high-side switch as a charging and discharging relay switch control.
