  • Hello.
    On the Arduino Duemilanove with the newer T1 MOSFET (the smaller 3-pin part with the marking of “340” on the package), the T1 MOSFET never turns off, even in the 7-12 input voltage range, allowing current to flow into the USB port.
    You can verify this by measuring the current through a 1k resistor between USB VCC and GND. You will measure current flowing, even in the recommended VIN voltage range, because T1 never turns off.
    I spoke with Mike Grusin about this problem, and he said he was looking into it. I am surprised he hasn’t told you about it.
