If they are empty, they cause additional current flow. At least there would be large voltage peaks then No abstract text available Text: Your fuse protects the onewire cable, not the interface circuit.

The single-channel versionDSthe duration of the active pullup is fixed on the DS Your laptop however, may use such a switch — because a molt fuse is inconvenient in a laptop — and thus, cause problems. DS 0x 0x 0x04FA. Return to Datasheey Products from Adafruit. The DS surrounding hardware? In case a device has a failure, the usb driver can turn off the power for the specific port. But the power supply on the usb-bus is on all the time. The DS supports a strong pullup and active pullup.

Because it will too lower the supply voltage about 0. If the power supply would sd2490 switched the choke coils would make bad things too.

You have to limit the current flowing into empty capacitors by applying a resistor or better a choke coil to the supply lines. Anyway, just posting as reference in case anyone else is wanting to do the same thing. In the meantime i’ve tried to increase the capacitors in the 5V Power supply line and after the 3,3V Regulator which might be indeed a little bit small.
