USB Signals Descriptions
USB_0_1_OC# B44 I CMOS 3.3V Suspend/3.3V PU 10k to 3.3VSB Connect to Overcurrent of USB Power Switch
USB over-current sense, USB channels 0 and 1. A pull-up for this line
shall be present on the Module. An open drain driver from a USB
current monitor on the Carrier Board may drive this line low. Do not
pull this line high on the Carrier Board.
USB_2_3_OC# A44 I CMOS 3.3V Suspend/3.3V PU 10k to 3.3VSB Connect to Overcurrent of USB Power Switch
USB over-current sense, USB channels 2 and 3. A pull-up for this line
shall be present on the Module. An open drain driver from a USB
current monitor on the Carrier Board may drive this line low. Do not
pull this line high on the Carrier Board.
USB_4_5_OC# B38 I CMOS 3.3V Suspend/3.3V PU 10k to 3.3VSB Connect to Overcurrent of USB Power Switch
USB over-current sense, USB channels 4 and 5. A pull-up for this line
shall be present on the Module. An open drain driver from a USB
current monitor on the Carrier Board may drive this line low. Do not
pull this line high on the Carrier Board.
USB_6_7_OC# A38 I CMOS 3.3V Suspend/3.3V PU 10k to 3.3VSB Connect to Overcurrent of USB Power Switch
USB over-current sense, USB channels 6 and 7. A pull-up for this line
shall be present on the Module. An open drain driver from a USB
current monitor on the Carrier Board may drive this line low. Do not
pull this line high on the Carrier Board.
