  • Page 20: Power Supply And System Resets

    9. Power Supply And System Resets 9.1 Power Source The SOM-IMX8M-MINI have built-in power management function, so it is only need to provide a +5V power source to the SOM-IMX8M-MINI via the 5V input pins of the J1 connector. The power consumption is requested 2A/5V(10 W) at least for the IMX8M-MINI-SOM board to be working properly.

  • Page 21: System Resets

    10. System Resets 10.1 Power-on Reset This type of reset occurs when the power is initially applied to the SOM-IMX8M-MINI. As the supply voltage rises, the on-board PMIC holds the i.MX 8M MINI in reset until all the processor power supply voltages have risen above the appropriate voltage thresholds (90% of the nominal values).
