Overview
The PCA9450AHNY is a single-chip Power Management Integrated Circuit (PMIC) designed by NXP USA Inc. to support the i.MX 8M family of application processors. This PMIC is tailored for use in both 1 cell Li-Ion and Li-polymer battery portable applications, as well as 5 V adapter non-portable applications. It integrates multiple power management functions into a single chip, simplifying system design and reducing component count and board area.
