IoT Battery Booster

IoT Battery Booster | Nexperia, the leading expert in essential semiconductors, introduces game-changing NBM7100 and NBM5100 battery life boosting ICs. These revolutionary solutions extend the lifespan of non-rechargeable lithium coin cell batteries by up to 10x, outperforming competitors in the market. Moreover, they enhance peak output current capability by up to 25x, surpassing the performance of typical coin cells without a battery booster. With this unparalleled battery life extension, Nexperia significantly reduces battery waste in low-power Internet of Things (IoT) and portable applications. Additionally, coin cells now become a viable power source for applications that traditionally relied on larger AA or AAA batteries. Experience the unmatched efficiency of Nexperia’s advanced battery life and power boosters today. 

“Introducing this IoT Battery Booster product signals Nexperia’s further expansion into battery management solutions,” according to Dan Jensen, General Manager of Nexperia’s BG Analog and Logic ICs. “We are excited to unveil these innovative products complementary to our existing analog and logic products. The NBM7100 and NBM5100 significantly enhance coin cell performance which helps to help reduce battery waste in IoT, wearables and other consumer applications.”

CR2032 and CR2025 Lithium coin cells have higher energy density and longer shelf life. As a result, they are commonly used in low-power applications, including devices with Low Power Wi-Fi, LoRa, Sigfox, Zigbee, LTE-M1, and NB-IoT transceivers. However, these batteries have relatively high internal resistance and chemical reaction rates that reduce their usable capacity when under pulsed-load conditions. To overcome this limitation, the NBM7100 and NBM5100 contain two high-efficiency DC/DC conversion stages and an intelligent learning algorithm. The first conversion stage transfers energy from the battery to a capacitive storage element at a low rate. The second stage utilizes the stored energy to provide a regulated (programmable from 1.8 V to 3.6 V) high pulse (up to 200 mA) current output. The intelligent learning algorithm monitors the energy used during repetitive load pulse cycles and optimizes first stage DC/DC conversion to minimize the residual charge in the storage capacitor. When not performing an energy conversion cycle (standby state), these devices consume less than 50 nA.

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 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 NBM5100Aand serial peripheral interface (SPI) in NMB7100Band 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.
