Multicell Li-Ion and Li-Pol Battery Gas-Gauge Application Using the bqJunior

The bqJunior™ series of gas gauges are designed to operate from a single-cell lithium-ion or lithium-polymer battery. Many applications that could benefit from using these gas gauges use two or more lithium cells in series where the battery voltage exceeds the operating voltage for the bqJunior™ gas gauges. This application report describes a low-component count solution for using th
