NBM7100A - Coin cell battery life booster

Datasheet Summary

Description

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.

Features

  • Programmable constant battery load current: 2 mA to 16 mA.
  • Protection against battery voltage dips (Brown-out).
  • Pulse output current: > 200 mA.
  • Low ripple regulated programmable output voltage, VDH: 1.8 V to 3.6 V.
  • Ultra-low standby current: 20 nA (typ).
  • Peak conversion efficiency up to 93% with adaptive optimization.
  • Integrated fuel gauge.
  • Small 16 pin lead-free package (SOT763-1/DHVQFN16; 2.5 mm × 3.5 mm × 0.85 mm).

NBM7100A; NBM7100B Coin cell battery life booster with adaptive power optimization Rev. 3 — 10 April 2025 Product data sheet 1. General description 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 overcome 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. 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.
