NBM7100A Overview
The NBM7100A/B is a battery energy management device designed to maximize usable capacity from non-rechargeable, primary batteries when used in lowvoltage, low-power applications requiring burst current loads. The devices overe voltage drop and battery life limitations associated with extracting high pulse currents (Fig. 1) from lithium primary batteries such as 3 V lithium manganese dioxide (LiMnO2) coin cells.
NBM7100A Key Features
