Hello, I have inherited a project which contains a Beaglebone Black within the design. I have no particular knowledge of the beaglbone.
I am attempting to design a power backup for the beaglebone to ensure corruption does not occur when power is lost. I understand this can happen. Apparently it has happened with this product. For that, I'm looking to use a relatively new device from LT being LTC3643. Basically, it charges a capacitor/super-cap arrangement during one mode, discharges the supper-cap by regulating to the load in another mode when the power is lost. Seeming quite nice. I've been looking through the pages and pages of information to determine the following questions about the beaglebone. Q1. In the real world, how long does the beaglebone black take to shutdown? Q2. Apparently the power button is held down for 8 seconds. Does this shutdown period commence from the end of that 8 seconds? Q3. From the notes left to me, I'm assuming the continuous current consumption to be 500mA at the 5V supply. Would anyone have an idea of what that may be during the shutdown period. Ultimately, I'm attempting to determine some supercap sizing here.
