Optimized for maximum efficiency and compact size, the nPM1304 is configurable via an I2C-compatible two-wire interface (TWI). This interface provides easy access and configuration of a range of advanced system management features, including integrated hard reset functionality for one or two buttons, accurate battery fuel gauge, system-level watchdog, power failure warning, and recovery after a failed boot.
These features are typically implemented as discrete components in embedded designs, but the nPM1304 integrates them into a single, compact package, simplifying system design - reducing the number of components required. The accompanying nPM1304-EK evaluation kit further supports developers in implementing their designs. The nPM1304 manages power for Nordic's nRF52, nRF53 and nRF54 series of wireless systems-on-chip (SoCs) and other microcontrollers (MCUs) with extremely low power consumption.
