IC FUEL GAUGE LI-ION 1CL 9DSBGA

The Li-ion battery charge monitors use the patented Impedance Trackâ„¢ algorithm for battery fuel gauging, and provide information such as remaining battery capacity (mAh), state-of-charge (%), and battery voltage (mV). It minimises dependence on host processor and improves standby power.
Safety protections such as over/under-​temperature, extra levels of over/under-voltage, discharge short circuit, charge overcurrent. Autonomously measures all cell voltages, integrated pack current and temperature every 1 second. Capacity Indication with advanced algorithms. Accurate battery State-Of-Health (SOH) enables accurate prediction of available capacity. Smart charging and adaptability
