Hi,

Any reason why there is a pull down resistor on the LPC18xx input signal "USB0_PWR_FAULT" on the LPC1830 explorer board?

Unless I am mistaken this will read always as a power fault since the LPC18xx USB0_PWR_FAULT input is active LOW and the LM3526-H has an open drain output.
I am using a pull up on mine.  Please let me know if I read this wrong.

Thanks
