The PCA9450 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 5 V adapter nonportable applications.
The device provides six high-efficiency step-down regulators, five LDOs, one 400 mA load switch, 2 channel level translator and 32.768 kHz 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. This device is characterized across -40 °C to 105 °C ambient temperature range.
Part numbers include: PCA9450AAHN, PCA9450BHN, PCA9450CHN.
