nPM2100 is an integrated Power Management IC (PMIC) designed for primary (non-rechargeable) batteries in an extremely compact form factor. It features an ultra-efficient boost regulator and a wide range of energy-saving features, extending the operating time for non-rechargeable battery applications.
nPM2100 provides power regulation for low-power microcontroller units (MCU) and System-on-Chip (SoC) devices, like the nRF52, nRF53, and nRF54 Series advanced wireless multiprotocol SoCs from Nordic Semiconductor. The device is optimized for maximum efficiency and uses an I2C compatible two-wire interface (TWI) for configuration. This interface enables easy access to a range of advanced functions, including Ship mode.
The boost regulator provides output voltages in the range of 1.8 V to 3.3 V and supports automatic Pass-through mode when the battery voltage exceeds the target output voltage. nPM2100 also includes a load switch/LDO that supports up to 50 mA output current and output voltages in the range of 0.8 V to 3.0 V.
nPM2100 supports battery voltages up to 3.4 V and can run from batteries such as one or two alkaline AA/AAA in series or one CR2032. It is able to start-up from 0.8 V battery voltage and run down to 0.7 V.
nPM2100 measures temperature and battery voltage, supporting algorithm-based fuel gauging. This is a unique feature in primary batteries for monitoring the state-of-charge in a non-rechargeable battery more accurately and eliminates unnecessary battery replacements.
Products can be shipped with the battery installed when using Ship mode. Ship mode supports sleep current down to 35 nA with multiple wakeup options, including a break-to-wake function that wakes a product from Ship mode when an electrical connection is broken. Hibernation mode uses an ultra-low power wakeup timer that enables timed wakeups. It provides lower power consumption than an SoC or MCU power-down.
The PMIC also features two GPIO pins that can control time-critical functions as an alternative to serial communication.
Application examples for nPM2100 include computer peripherals/HID, remote controls, smart home sensors, Bluetooth® Low Energy asset tracking, fitness accessories and personal medical devices.
