NBM5100BBQ-Q100X

NBM5100BBQ-Q100X 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 3.6V lithium thionyl chloride (Li-SOCl2), 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. Typical applications include battery powered wireless microcontroller applications (IoT): Bluetooth®, LoRaWAN®, Sigfox™, LTE-M, NB-IoT, ZigBee, industrial: temperature, occupancy, e-metering, electronic shelf label, asset tracking, irrigation monitoring, automotive: tire pressure monitors (TPMS), key fobs.
