PCA9450AAHNY

PCA9450AAHNY is a single-chip power management IC (PMIC) specifically designed to support i.MX 8M family processor in both 1 cell Li-ion and Li-polymer battery portable application and 5V adapter non-portable applications. It supports various memory types (DDR4/LPDDR4/DDR3L, etc.) via system UBOOT configuration, which does not require hardware change. This device provides six high-efficiency step-down regulators, five LDOs, one 400mA load switch, 2-channel level translator and 32.768KHz crystal oscillator driver. Three buck regulators support dynamic voltage scaling (DVS) feature along with programmable ramping up and down time and those buck regulators support remote sense to compensate IR drop to load from buck regulator. Applications include IoT devices, tablet, electronic point of sale (ePOS), industrial application.
