PCA9452AHNE

PCA9452AHNE is a power management IC for i.MX 93 application processor. The PCA9452 is a single chip AEC Q100 grade 2 automotive Power Management IC (PMIC) specifically designed to support i.MX 93x family processor in automotive applications. The 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. Six step-down regulators are designed to provide power for i.MX 93x application processor and DRAM memory. Typical applications include automotive infotainment, heads up display (HUD), GPS and monitoring system.
