... Off or Amber, if due to an Off Overcurrent Condition Document #: 38-08037 Rev. *H The OVR[n]# pins of the CY7C656xx series are connected to the respective external power switch's port over-current indication (output) signals. Upon detecting an over-current condition, the hub reports the overcurrent condition to the host and disables the PWR# output to the external power device. ...
