The USB specification requires that it will operate between 4.5 and 5.5 Volts.
For the 5 Volt power jack, the PMIC will operate between 4.5 and 5.5 Volts. BUT, the PMIC will shut down and go into self protection above or below those Voltages. So, in order to allow for some noise and Voltage spikes, so that you have margin against the shut down points, I recommend that you operate the Power Jack and USB between 4.75 and 5.25 Volts. Physical damage will not occur until at least 7 Volts, but it will self protect (turn itself off) starting at 5.50 Volts If you question has to do with running the BBB from batteries, I suggest that you have an external boost/buck converter, so that the power to the BBB stays at a safe and comfortable 4.75 to 5.25 Volts, no matter what the battery is doing. --- Graham == On Thursday, August 10, 2017 at 1:43:05 AM UTC-5, Fohnbit wrote: > > Hello, > > which Range is supported at the USB and power jack input? > 5V or cource ... but in which range before the board will be damaged? > 4.5 - 5.5V ? > > Thank you! > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
