This document provides guidelines for the hardware design and integration of the nPM1300 and nPM1304 Power Management Integrated Circuit (PMIC)s. It is intended for system integrators and hardware engineers.
The PMIC has a linear-mode battery charger suitable for Lithium-ion (Li-ion), Lithium-polymer (Li-Poly), and Lithium iron phosphate (LiFePO4) batteries. It comes in a compact 5 mm x 5 mm Quad Flat No-lead Package (QFN) or a 3.1 mm x 2.4 mm Wafer Level Chip Scale Package (WLCSP) supplemented with regulated supplies, load switches, and a variety of system management features.
The PMIC has two highly efficient dual mode DC/DC buck regulators with configurable output. The buck regulators have automatic mode switching from hysteretic to Pulse Width Modulation (PWM) depending on load condition.
