In the 3rd video, we’ll explain the multiple voltage rails and power sequence requirements of the MTK car infotainment system board and how to accomplish this via a special multi rail PMIC sequencer IC. We’ll show how change the functionality by reprogramming the PMIC MTP memory and check the power sequence during cold cranking.
