Nexperia introduces industry’s first coin cell battery life and power booster IC

July 11, 2023 /SemiMedia/ — Nexperia lately introduced the NBM7100 and NBM5100, revolutionary new sorts of battery life boosting ICs designed to increase the lifetime of a typical non-rechargeable lithium coin cell battery by as much as 10x in comparison with competing options whereas additionally rising its peak output present functionality by as much as 25x in comparison with what a typical coin cell can ship with out a battery booster.  This unrivalled extension in working life will considerably cut back the quantity of battery waste in low-power Web of Issues (IoT) and different moveable functions whereas making coin cells a viable energy supply for functions which may beforehand solely function from AA- or AAA- batteries.  

“Introducing this battery life booster product alerts Nexperia’s additional enlargement into battery administration options,” in accordance with Dan Jensen, Basic Supervisor of Nexperia’s BG Analog and Logic ICs. “We're excited to unveil these progressive merchandise complementary to our present analog and logic merchandise. The NBM7100 and NBM5100 considerably improve coin cell efficiency which helps to assist cut back battery waste in IoT, wearables and different client functions.”

CR2032 and CR2025 Lithium coin cells have larger power density and longer shelf life. In consequence, they're generally utilized in low-power functions, together with gadgets with Low Energy Wi-Fi, LoRa, Sigfox, Zigbee, LTE-M1, and NB-IoT transceivers. Nevertheless, these batteries have comparatively excessive inside resistance and chemical response charges that cut back their usable capability when beneath pulsed-load circumstances. To beat this limitation, the NBM7100 and NBM5100 include two high-efficiency DC/DC conversion phases and an clever studying algorithm. The primary conversion stage transfers power from the battery to a capacitive storage component at a low price. The second stage makes use of the saved power to supply a regulated (programmable from 1.8 V to three.6 V) excessive pulse (as much as 200 mA) present output. The clever studying algorithm screens the power used throughout repetitive load pulse cycles and optimizes first stage DC/DC conversion to attenuate the residual cost within the storage capacitor. When not performing an power conversion cycle (standby state), these gadgets eat lower than 50 nA.

Each gadgets are specified over -40 °C to 85 °C, making them appropriate for industrial indoor and industrial out of doors environments. A ‘low battery’ indicator alerts the system when the battery reaches its useful endpoint. As well as, brownout safety inhibits charging of the storage capacitor when the battery is close to the tip of its life.

A serial interface is included for configuration and management by a system microcontroller: I2C in NMB7100A and NBM5100A and serial peripheral interface (SPI) in NMB7100B and NBM5100B variations. Each gadgets can lengthen the lifetime of energy-dense Lithium major batteries, together with coin cells, Lithium Thionyl (ex: LS14250 1/2 AA) and rising paper printed sorts, thus lowering upkeep by extending the time interval between battery replacements. As well as, the NBM5100A/B features a capacitor voltage balancing pin for super-capacitor-based implementations.

The NBM5100A/B and NBM7100A/B battery boosters can be found in a small DHVQFN16 package deal measuring 2.5 mm × 3.5 mm × 0.85 mm.
