Change non-rechargeable batteries less often with power management IC

The ultra-efficient boost regulator in the nPM2100 PMIC enables longer run time for single-use batteries which include a single, or series of two, AA or AAA batteries, a 3V CR2032 coin-cell, as well as single- or dual-cell silver oxide and zinc-air coin cell batteries. The nPM2100 PMIC can also be used with any other battery operating in the PMIC input voltage range from 0.7V to 3.4V.

Output voltage is from 1.8V to 3.3V and the quiescent current of 150nA makes the internal boost regulator among the most efficient boost regulators. The 35nA ship mode allows the application to be shipped with the batteries inserted and without draining the battery. This also eliminates the plastic pull-tab which is used to protect batteries during shipment and storage. The hibernate mode offers timed wakeups from deep sleep, which lowers sleep current to 175nA. This battery-saving mode can extend battery lifetimes by up to 3x.

Precise algorithm-based fuel gauging is featured in the nPM2100 PMIC. Full battery use with minimal additional load is achieved by using a voltage and temperature-based fuel gauge on the host microprocessor to give more accurate readings than standard voltage-based estimation. The inaccuracy of voltage-based estimation can lead to premature battery replacement or unexpected depletion.

The use of the nPM2100 PMIC can also enable a design to use smaller batteries which give the same battery life, so the end product can be designed to be smaller, lighter and at less cost.

The nPM2100 can manage the power supply to low-power systems-on-chip (SoCs) or microcontrollers (MCUs). These include the Nordic advanced multiprotocol wireless nRF52, nRF53, and nRF54 SoCs, with software support from the nRF Connect SDK.
