NBM7100BBQ

NBM7100BBQ is a coin cell battery life booster with adaptive power optimization. It is a battery energy management device designed to maximize usable capacity from non-rechargeable, primary batteries when used in low-voltage, low-power applications requiring burst current loads. The device overcomes voltage drop and battery life limitations associated with extracting high pulse currents from lithium primary batteries such as 3V lithium manganese dioxide coin cells. which are commonly used in wireless, low-power IoT sensor applications. It contains two stages of high-efficiency DC-DC conversion and an intelligent learning algorithm. The application includes battery-powered wireless microcontroller applications (IoT): Bluetooth®, LoRaWAN®, Sigfox™, LTE-M, NB-IoT, Zigbee, etc., temperature, occupancy, e-metering, electronic shelf label, asset tracking, irrigation monitoring (industrial), consumer/wearable: location tags, heart rate monitor, blood glucose meter, remote controls, key fobs.
