Nexperia unveils industry’s first coin cell battery life and power booster

The NBM7100 and NBM5100, are 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 unrivaled 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 that could previously only operate from AA- or AAA- batteries.

The NBM7100A/B contains two stages of high-efficiency DC-DC conversion and an intelligent learning algorithm. The first stage DC-DC conversion transfers energy from the lithium battery at a low constant current to a capacitive storage element. Once charged, a second DC-DC conversion cycle utilizes this stored energy to supply a regulated voltage with high pulse load current capability on the VDH output pin. The battery is never directly subjected to large load pulse currents, resulting in a longer, more predictable battery lifetime.
