1 AM62Ax Maximum Current Ratings

The table summarizes the maximum current ratings at the AM62Ax power terminals. The data in this table serves as a guide for designing power supplies. The current ratings in the table are worst-case estimates for each power supply group, and actual power supply currents for specific applications are typically lower. For further details, please refer to the AM62Ax Power Estimation Tool.

(1) VDD_CANUART shall be combined with the VDD_CORE power supply group and VDDSHV_CANUART shall be combined with the I/O Power Supply group when not using Partial IO low power mode.

(2) VDDR_CORE shall be combined with VDD_CORE power supply group when VDD_CORE is used in 0.85 V.

(3) VDDSHV5 shall be combined with the I/O Power Supply group when a separate power supply is not required for voltage scaling for a high-speed SD card.

(4) VDDA_MCU shall be combined with the same power supply group with the 1.8-V Analog Power Supply and VDDSHV_MCU shall be combined with the I/O Power Supply Group when not isolating MCU channel IO from other IO groups.
