... Port Power Control Using a USB Power Switch The LAN9512 has a single port power control and over-current sense signal for each downstream port. When disabling port power the driver will actively drive a ‘0’. To avoid unnecessary power dissipation, the internal pull-up resistor will be disabled at that time. When port power is enabled, the output driver is disabled and the pull-up resistor is enabled, creating an open drain output ...
Page 17
... Port Power Control Using a Poly Fuse When using theLAN9512 with a poly fuse, an external diode must be used (See disabling port power, the driver will drive a ‘0’. This procedure will have no effect since the external diode will isolate the pin from the load. When port power is enabled, the output driver is disabled and the pull-up resistor is enabled, which creates an open drain output ...

... Note: Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on internal resistors to drive signals external to LAN9512. When connected to a load that must be pulled high, an external resistor must be added. PD 50uA (typical) internal pull-down. Unless otherwise noted in the pin description, internal pull-downs are always enabled ...
