Nordic Semiconductor nPM2100 Power Management ICs

Nordic Semiconductor nPM2100 Power Management ICs (PMICs) incorporate an ultra-efficient boost regulator and a range of energy-saving features to extend operating time significantly in non-rechargeable battery applications. The nPM2100 manages the power supply for low-power Systems-on-Chip (SoCs) or microcontrollers (MCUs). The PMIC is optimized for maximum efficiency and compact size and is configurable through an I2C-compatible Two Wire Interface (TWI). This interface enables easy access to configure advanced functions, including ship mode and accurate battery fuel gauging. The PMIC also provides two GPIOs that can be repurposed to direct control lines to time-critical control functions as an alternative to serial communication. Application examples for the Nordic nPM2100 include wireless mice/keyboards, consumer asset tracking, remote controls, and body-worn medical devices.

Features

  • Extends operating time in non-rechargeable battery applications
  • TWI interface offers easy access to advanced features
  • Two GPIOs can direct control lines to time-critical control functions
  • Boost regulator
    • 1.8V to 3.3V output range
    • 0.7V to 3.4V input range
    • Delivers up to 150mA maximum current
    • Powers a load switch/LDO supplying up to 50mA
  • Low-current ship mode
    • Enables products to be transported with the battery inserted
    • Ship mode supports a 35nA sleep current with multiple wakeup options
  • Ultra-low power wake-up timer
    • Can run concurrently with ship mode to allow timed wakeups
    • Timer can be used for a deeper sleep setting than the power-off of a SoC or MCU can provide

Applications

  • Wireless mice and keyboards
  • Consumer asset tracking
  • Remote controls
  • Body-worn medical devices
