Nordic Semiconductor nPM1300 Power Management ICs (PMICs) integrate essential functions required for BLUETOOTH® Low Energy embedded designs while supporting long run times and efficient battery charging. The Nordic nPM1300 is configurable via an I2C-compatible Two-Wire Interface (TWI). This interface enables easy access and configuration of various advanced system management functions. These system management functions include a two-button hard reset, battery fuel gauging, a system-level watchdog, a power-loss warning, and failure-boot recovery. These functions are typically implemented as discrete components in BLUETOOTH Low Energy (LE) embedded design. Still, the nPM1300 PMIC integrates them into a single, compact package, simplifying system design and reducing the required components.
