Nexperia Battery management ICs

The NBM7100 and NBM5100, revolutionary new types of battery life boosting ICs designed to extend the life of a typical non-rechargeable lithium coin cell battery by up to 10x compared to competing solutions while also increasing its peak output current capability by up to 25x compared to what a typical coin cell can deliver without a battery booster. This unrivalled extension in working life will significantly reduce the amount of battery waste in low-power Internet of Things (IoT) and other portable applications while making coin cells a viable power source for applications which could previously only operate from AA- or AAA- batteries.
