NBM7100ABQ

Coin cell battery life booster with adaptive power optimization

The NBM7100A/B 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 devices overcome voltage drop and battery life limitations associated with extracting high pulse currents (Figure 1) from lithium primary batteries such as 3 V lithium manganese dioxide (LiMnO2) coin cells. which are commonly used in wireless, low-power IoT sensor applications.

The NBM7100A/B contains two stages of high efficiency DC-DC conversion and an intelligent learning algorithm. The first stage DC-DC conversion transfers energy from the lithium battery at a low constant current to a capacitive storage element. Once charged, a second DC-DC conversion cycle utilizes this stored energy to supply a regulated voltage with high pulse load current capability on the VDH output pin. The battery is never directly subjected to large load pulse currents, resulting in a longer, more predictable battery lifetime.

The proprietary 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.

A serial interface allows a microcontroller to change default configuration settings and read-back system information.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
