the NBM7100 and NBM5100, 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 extension in working life will significantly reduce the amount of battery waste in low-power 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. 

Both devices are specified over -40°C to 85°C, making them suitable for commercial indoor and industrial outdoor environments. A ‘low battery’ indicator alerts the system when the battery reaches its functional endpoint. In addition, brownout protection inhibits the charging of the storage capacitor when the battery is near the end of its life.

A serial interface is included for configuration and control by a system microcontroller: I2C in NMB7100A and NBM5100A and serial peripheral interface (SPI) in NMB7100B and NBM5100B versions. Both devices can extend the lifetime of energy-dense Lithium primary batteries, including coin cells, Lithium Thionyl (ex: LS14250 1/2 AA) and emerging paper printed types, thus reducing maintenance by extending the time interval between battery replacements. In addition, the NBM5100A/B includes a capacitor voltage balancing pin for super-capacitor-based implementations.
