nPM2100 PMICs

The Nordic Semiconductor nPM2100 is a power management IC (PMIC) with an ultra-efficient boost regulator for primary-cell batteries.

It features one boost converter that can provide voltages of 1.8 V to 3.3 V output from input voltages of 0.7 V to 3.4 V. Examples of supported batteries are one or two AA/AAA batteries (in series) or one 3 V CR2032 cell. Single- or dual-cell silver oxide and zinc-air coin-cell batteries are also supported, as well as any other battery that operates within the PMIC's input voltage range.

The 150 nA IQ internal boost regulator places itself among the most efficient boost regulators on the market today. A 35 nA ship mode allows the device to be shipped with batteries inserted without draining the battery and eliminates the plastic pull-tab method of protecting batteries during shipping and storage. Hibernate mode includes timed wakeups for applications that spend most of their time in deep sleep, lowering sleep current to 175 nA while extending battery lifetimes by up to 3x.

The nPM2100 evaluation kit allows for simple evaluation and code-free configuration of the nPM2100 PMIC. By connecting to the nPM PowerUP app found in nRF Connect for Desktop, all settings of the nPM2100 can easily be configured through an intuitive GUI and exported as code to be implemented in the MCU's application.

The kit includes add-on boards to connect AA, AAA, LR44, and CR2032 batteries for easy evaluation of the nPM2100 with combinations of non-rechargeable batteries. In all, the kit comes with six battery holders for one or two AA or AAA batteries in series, as well as holders for 20-mm-diameter coin-cells like CR2032 and 11.6 mm button-cells like LR44.
