The automotive off-battery processor power reference design provides a versatile protected power tree for supplying common Advanced Driver Assistance Systems (ADAS) and infotainment processors, such as TDA4x-Q1 and AM6x-Q1. The processors described work with sensor fusion systems, camera modules and domain controllers. Detailed guidance helps designers create protected power systems. Additional power rails are provided for Double Data Rate (DDR) memory and auxiliary loads. The design contains an onboard MSPM0 microcontroller (MCU) for programming the power rail voltages and sequencing.
