nPM1300 Power Management IC

Highly integrated PMIC with unique system management features.

The nPM1300 is a highly integrated multifunction Power Management IC (PMIC) that includes battery charger, an algorithm-based fuel gauge, two ultra-efficient buck regulators, two LDOs / load switches, and comprehensive system management functions into a single device. The nPM1300 reduces both board space and bill of materials while replacing multiple discrete components while enabling greater design flexibility through a fully I²C-compatible TWI interface. 

The nPM1300 includes an algorithm-based battery fuel gauge solution with state of charge and state of health reporting. It comes with coulomb counter accuracy, ultra-low power operation and does not require any extra components. A rich set of system management features including a hardware watchdog, power loss warning, hard reset supervisory circuit, failed boot recovery, ship and hibernate modes.
